Hi,

I'm encountering this internal compiler error with gcc 11.2.0. I'm not quite
sure how to provide more information.

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is rather interesting as usually inline asm would not cause an
unrecognizable insn error.

>I'm not quite sure how to provide more information.

The first thing you could do is say if this is private software or open source.
If it is private software you might want to read
https://gcc.gnu.org/wiki/A_guide_to_testcase_reduction#Reducing_LTO_bugs and
try to reduce the sources yourself.

Otherwise reporting the exact version of the source you used, for both the open
source software and GCC.

For GCC you can provide the output of "armv7em-linux-musleabihf-g++ -v" as a
start.

It's open source, but probably a bit of work to reproduce. I'll see if I can
produce a reduced testcase. Thanks for the link to the instructions.

I'm a little stuck with trying to reduce this.

The instructions linked say to look at "@/tmp/ccXXXXX" to get a list of object
files of interest. In this case the lto1 invocation which is failing only has
one object file in the command file @apex/sys/apex.elf.ltrans1.ltrans.args.0:

% cat apex/sys/apex.elf.ltrans1.ltrans.args.0
apex/sys/apex.elf.ltrans1.o

Am I missing something?

The first thing to reducing this is reducing the number of object files in use.
instead of doing a full link you could use -r and try removing object files
until it does not fail.

Try the following two object files:
/home/patrick/src/apex-examples/apex/sys/kern/timer.cpp
/home/patrick/src/apex-examples/apex/sys/arch/arm/v7em/atomic.cpp

At least attach the preprocessed source for these two. I might be able to help
with a testcase.

I am thinking the function in atomic.cpp is being inlined into timer.cpp and
the inline-asm with the volatile memory location is causing issues.

r10-3984-g22060d0e575e7754eb1355763d22bbe37c3caa13 already ICEs.

I guess there is a disagreement between LRA and recog on how exactly they treat
register constraints.
"=lh" for TARGET_THUMB means LO_REGS or HI_REGS classes for the output, bet LRA
sees that LO_REGS or HI_REGS is together GENERAL_REGS and picks a GENERAL_REGS
(reg:DI 7 r7 [orig:119 tmp ] [119]).  But that one has one half in LO_REGS and
another half in HI_REGS and so extract_constrain_insn -> constrain_operands
doesn't consider it as matching.

Interesting case.  To find required (reload) register class, LRA (as also the
old reload pass) makes some union of register classes in one alternative which
contains all or part of the registers of the classes (in this case it is
general reg class).  The problem can be solved w/o fixing LRA (and reload pass)
by using

 asm volatile(
  "ldrd %Q[r], %R[r], %[p]\n"
  : [r]"=l,h"(tmp)
  : [p]"m,m"(*p64)
  : "memory"
 );

The problem can be solved in LRA by more complex representation of required reg
classes (still reload should have also such fix).  I guess it will complicate
LRA and reload code a lot.

We could also use more clear description of semantics of constraints currently
used by LRA/reload.  In this case we still need to output more meaningful error
for LRA/reload instead of just internal compiler error.

If we consider such an inline asm invalid, we could error on it, ICE is not the
right thing.  But what exactly should we error on?  Alternative containing
multiple register classes for multi-word operands is still something used quite
commonly in real-world, the problem is when the RA assigns it a reg spanning
across those.  Or do most backends restrict multi-word regs to start at a reg
number divisible by the number of words they need?

I think it is better to fix it in LRA than describing the semantics.  I am
starting to work on it and will look how the fix is going.  If it is too
complicated, we could try another solution (with describing the current
semantics).

In any case, I think it is not worth to fix the same existing problem in the
old reload pass.

    [PR103676] LRA: Calculate and exclude some start hard registers for reload
pseudos

    LRA and old reload pass uses only one register class for reload pseudos
even if
    operand constraints contain more one register class.  Let us consider
    constraint 'lh' for thumb arm which means low and high thumb registers.
    Reload pseudo for such constraint will have general reg class (union of
    low and high reg classes).  Assigning the last low register to the reload
    pseudo is wrong if the pseudo is of DImode as it requires two hard regs.
    But it is considered OK if we use general reg class.  The following patch
    solves this problem for LRA.
