Here's v2 of the series to rewrite gdbarch.sh in Python. I think this
version addresses all the review comments.
Let me know what you think.

While I think it makes sense to generate gdbarch.c, at the same time I
think it is better for ordinary code to be editable in a C file -- not
as a hunk of C code embedded in the generator.
This patch moves this sort of code out of gdbarch.sh and gdbarch.c and
into arch-utils.c, then has arch-utils.c include gdbarch.c.

* [PATCH v2 2/8] Split gdbarch.h into two files
2021-12-16 20:38 [PATCH v2 0/8] Rewrite gdbarch.sh in Python Tom Tromey
2021-12-16 20:38 ` [PATCH v2 1/8] Move ordinary gdbarch code to arch-utils Tom Tromey

From: Tom Tromey @ 2021-12-16 20:38 UTC (permalink / raw)
To: gdb-patches; +Cc: Tom Tromey
This patch splits gdbarch.h into two files -- gdbarch.h now is
editable and hand-maintained, and the new gdbarch-gen.h file is the
only thing generated by gdbarch.sh. This lets us avoid maintaining
boilerplate in the gdbarch.sh file.
Note that gdbarch.sh still generates gdbarch.h after this patch. This
makes it easier to re-run when rebasing. This code is removed in a
subsequent patch.

- register allocation and use smaller registers than necessary. In
- such cases, the client that is reading and evaluating the SystemTap
- probe (ourselves) will need to actually fetch values from the wider
- version of the register in question.
-
- To illustrate the example, consider the following probe argument
- (i386):
-
- 4@%ax
-
- This argument says that its value can be found at the %ax register,
- which is a 16-bit register. However, the argument's prefix says
- that its type is "uint32_t", which is 32-bit in size. Therefore, in
- this case, GDB should actually fetch the probe's value from register
- %eax, not %ax. In this scenario, this function would actually
- replace the register name from %ax to %eax.

Now that gdbarch.h has been split, we no longer need the generator
code in gdbarch.sh, so remove it.

This changes gdbarch.sh so that it no longer sorts the fields in
gdbarch_dump. This sorting isn't done anywhere else by gdbarch.sh,
and this simplifies the new generator a little bit.

From: Tom Tromey @ 2021-12-16 20:38 UTC (permalink / raw)
To: gdb-patches; +Cc: Tom Tromey
The new gdbarch.sh approach will be to edit a Python file, rather than
adding a line to a certain part of gdbarch.sh. We use the existing sh
code, though, to generate the first draft of this .py file.
Documentation on the format will come in a subsequent patch.
Note that some info (like "staticdefault") in the current code is
actually unused, and so is ignored by this new generator.

+and so on). It should also return 1 if the parsing was successful, or zero

+Perform arch-dependent adjustments to a register name.
+
+In very specific situations, it may be necessary for the register

+register allocation and use smaller registers than necessary. In
+such cases, the client that is reading and evaluating the SystemTap
+probe (ourselves) will need to actually fetch values from the wider
+version of the register in question.
+
+To illustrate the example, consider the following probe argument
+(i386):

+4@%ax
+
+This argument says that its value can be found at the %ax register,

+%eax, not %ax. In this scenario, this function would actually

From: Simon Marchi <simon.marchi@efficios.com>
The new gdbarch generator is a Python program. It reads the
"components.py" that was created in the previous patch, and generates
gdbarch.c and gdbarch-gen.h.
This was initially written by Simon, so I've put him as the author.
Thank you, Simon.
This is a relatively straightforward translation of the existing .sh
code. It doesn't try very hard to be idiomatic Python or to be
especially smart.
It is, however, incredibly faster:
$ time ./gdbarch.sh
real 0m8.197s
user 0m5.779s
sys 0m3.384s
$ time ./gdbarch.py
real 0m0.065s
user 0m0.053s
sys 0m0.011s

A "special case" is considered to be an unknown token, i.e., a token
that the parser does not know how to parse. A good example of special
case would be ARM's register displacement syntax:
-

-
+
+ <number> <indirection_prefix> <register_name> <indirection_suffix>

it means that it will not be able to recognize and parse this odd syntax.
Therefore, we should add a special case function that will handle this token.

This argument says that its value can be found at the %ax register,

that its type is "uint32_t", which is 32-bit in size. Therefore, in
this case, GDB should actually fetch the probe's value from register
%eax, not %ax. In this scenario, this function would actually
replace the register name from %ax to %eax.

-# case would be ARM's register displacement syntax:
-#
-# [R0, #4] ;; displacing R0 by 4

-#
-# it means that it will not be able to recognize and parse this odd syntax.
-# Therefore, we should add a special case function that will handle this token.
-#
-# This function should generate the proper expression form of the expression
-# using GDB\'s internal expression mechanism (e.g., \`write_exp_elt_opcode\'
-# and so on). It should also return 1 if the parsing was successful, or zero
-# if the token was not recognized as a special token (in this case, returning
-# zero means that the special parser is deferring the parsing to the generic
-# parser), and should advance the buffer pointer (p->arg).

-# Perform arch-dependent adjustments to a register name.

-# In very specific situations, it may be necessary for the register

-# special way. For example, on i386, GCC may over-optimize the
-# register allocation and use smaller registers than necessary. In
-# such cases, the client that is reading and evaluating the SystemTap
-# probe (ourselves) will need to actually fetch values from the wider
-# version of the register in question.
-#
-# To illustrate the example, consider the following probe argument
-# (i386):
-#
-# 4@%ax
-#
-# This argument says that its value can be found at the %ax register,
-# which is a 16-bit register. However, the argument's prefix says
-# that its type is "uint32_t", which is 32-bit in size. Therefore, in
-# this case, GDB should actually fetch the probe's value from register
-# %eax, not %ax. In this scenario, this function would actually
-# replace the register name from %ax to %eax.

# You should have received a copy of the GNU General Public License

+# How to add to gdbarch:
+#
+# There are four kinds of fields in gdbarch:
+#
+# * Info - you should never need this; it is only for things that are
+# copied directly from the gdbarch_info.
+#
+# * Value - a variable.
+#
+# * Function - a function pointer.
+#
+# * Method - a function pointer, but the function takes a gdbarch as
+# its first parameter.
+#
+# You construct a new one with a call to one of those functions. So,
+# for instance, you can use the function named "Value" to make a new
+# Value.
+#
+# All parameters are keyword-only. This is done to help catch typos.
+#
+# Some parameters are shared among all types (including Info):
+#
+# * "name" - required, the name of the field.
+#
+# * "type" - required, the type of the field. For functions and
+# methods, this is the return type.
+#
+# * "printer" - an expression to turn this field into a 'const char
+# *'. This is used for dumping. The string must live long enough to
+# be passed to printf.
+#
+# Value, Function, and Method share some more parameters. Some of
+# these work in conjunction in a somewhat complicated way, so they are
+# described in a separate sub-section below.
+#
+# * "comment" - a comment that's written to the .h file. Please
+# always use this. (It isn't currently a required option for
+# historical reasons.)
+#
+# * "predicate" - a boolean, if True then a _p predicate function will
+# be generated. The predicate will use the generic validation
+# function for the field. See below.
+#
+# * "predefault", "postdefault", and "invalid" - These are used for
+# the initialization and verification steps:
+#
+# A gdbarch is zero-initialized. Then, if a field has a pre-default,
+# the field is set to that value. After initialization is complete
+# (that is, after the tdep code has a change to change the settings),
+# the post-initialization step is done.
+#
+# There is a generic algorithm to generate a "validation function" for
+# all fields. If the field has an "invalid" attribute with a string
+# value, then this string is the expression (note that a string-valued
+# "invalid" and "predicate" are mutually exclusive; and the case where
+# invalid is True means to ignore this field and instead use the
+# default checking that is about to be described). Otherwise, if
+# there is a "predefault", then the field is valid if it differs from
+# the predefault. Otherwise, the check is done against 0 (really NULL
+# for function pointers, but same idea).
+#
+# In post-initialization / validation, there are several cases.
+#
+# * If "invalid" is False, or if the field specifies "predicate",
+# validation is skipped. Otherwise, a validation step is emitted.
+#
+# * Otherwise, the validity is checked using the usual validation
+# function (see above). If the field is considered valid, nothing is
+# done.
+#
+# * Otherwise, the field's value is invalid. If there is a
+# "postdefault", then the field is assigned that value.
+#
+# * Otherwise, the gdbarch will fail validation and gdb will crash.
+#
+# Function and Method share:
+#
+# * "params" - required, a tuple of tuples. Each inner tuple is a
+# pair of the form (TYPE, NAME), where TYPE is the type of this
+# argument, and NAME is the name. Note that while the names could be
+# auto-generated, this approach lets the "comment" field refer to
+# arguments in a nicer way. It is also just nicer for users.

Thanks, LGTM from my side. I noticed we are using some f-strings in the
code. They are available starting at Python 3.6. We support building
GDB against older Python libs than that (including Python 2.7, still).
But since this is a development-only dependency, and Python 3.6 has been
there for a while (it is the default python3 version in Ubuntu 18.04,
for example), I think this is ok.

FWIW I think the keyword-argument-only approach is also a Python 3-ism.

Perhaps, I didn't even know about this before reading your patch. I think
it's a good idea to force callers to be descriptive.

This gave me pause, until I saw an entry with more than one argument. Do you think it would be possible
to tweak the generator to avoid putting the comma after the last entry, so that we'd get:
params=(("readable_regcache *", "regcache")),
?
Also, I'd suggest putting params right after type, so that the function's prototype is all together:
I.e., instead of:
Method(

Return -1 for bad REGNUM. Note: Several targets get this wrong.
""",
name="dwarf2_reg_to_regnum",

predefault="no_op_reg_to_regnum",
invalid=False,
params=(("int", "dwarf2_regnr"),),
)
This:

The latter seems easier to eyeball to me.

This sentence will read funny once this is committed, since he's the commit author
and no other name appears in the commit log. Like, anyone reading this there will
go "but who is talking?" :-)
I'd remove it here and add your name as Co-Authored-By:.
This is all super awesome, BTW. Thank you both for doing this.

Haha, I agree :). Or you as the author and me as Co-Authored-By, since
you are the final author. Doesn't matter either way.

No, because that would not mean the same thing:
In [1]: ((1, 2),)
Out[1]: ((1, 2),)
In [2]: ((1, 2))
Out[2]: (1, 2)
The latter does not yield a tuple with a tuple with two integers, it
just yields a tuple with two integer. The outer parenthesis are
interpreted as "arithmetic" parenthesis (not sure how to call them, the
kind of parenthesis you use to force order of expression evaluation).
Having the comma there forces it to be interpreted as a tuple.

Sounds like a good idea to me, if it's not too difficult.

If you moved 'type' up you'd almost have it match what ends up in C:
Method(
comment="""
Provide a default mapping from a DWARF2 register number to a gdb REGNUM.
Return -1 for bad REGNUM. Note: Several targets get this wrong.
""",
type="int",
name="dwarf2_reg_to_regnum",
params=(("int", "dwarf2_regnr"),),
predefault="no_op_reg_to_regnum",
invalid=False,
)
But any order is fine really.

As Simon and John pointed out, this isn't possible due to a quirk of
Python syntax:
>>> (1,2) == ((1,2))
True
However we can use a list instead. This is mildly less idiomatic (it's
more normal, I think, to use tuples for non-extensible sequences) but
avoids the weirdess. This will look like
params=[("readable_regcache *", "regcache")]
I'll see if I can do this.

I did this. black likes to change:
params=[
x,
y,
z
]
into
params=[
x,
y,
z,
]
... when it decides that each entry should have its own line.
It's like putting the trailing comma into an enum in C.
Anyway I think this is decent, so I'm going to go forward with this and
check it all in.
