I'm an innocent bystander: I did not introduce
TDESC_SECTION_ASM_OP.  I see a ChangeLog(.4) entry of mine
vaguely related to TDESC_SECTION_ASM_OP, dated 2000-09-25: a
large patch where I added leading and trailing TAB characters to
most *ASM_OP macros.  Perhaps you meant some other macro?

This PR is targeted for 3.3.1, but I believe it is not reasonable to expect this
to be fixed before then; this PR is important for 3.4 and it really, _really_,
__REALLY__ should be fixed for 3.4.  But certainly not for 3.3.1.  So I moved
the target milestone.

Is the list of undocumented macros still up to date?  Is there a way to check
this quickly?

There really is no easy way to find out what are the new ones that got not documented, I 
tried to update the list that was there and add people who added some of the patches 
which added the target macros.

I'd prefer we leave this for 3.3.2, rather than 3.4, so that it shows up
on everyone's radar when they search for bugs to kill for the next
release.

The list in the bug report is a subset of my longer list (of the same
vintage) <http://gcc.gnu.org/ml/gcc/2001-06/msg00507.html> (linked to from
projects/beginner.html), from which I extracted those that weren't in 2.95
so that the bug was a regression.  That message describes the methodology
- that the macro is defined in a target header, used somewhere else in the
compiler, and not mentioned in the manual - the implementation was
probably a perl+shell one-liner on the command line with some subsequent
manual editing.

Other similar checks that can be done:

* Macros that are documented but not defined by any targets, or defined 
only with one default value (in which case the default should at least go 
to defaults.h if there is thought to be value in retaining the macro).

* Macros that are documented but not used in the compiler (whether or not
defined by targets).

* Macros that are defined in a target header but not used in the compiler 
(including in that config directory), whether or not documented.

* Macros that are tested in the compiler but not defined anywhere and not
documented.

I.e., if DOC is the set of all documented target macros (extracted from 
the manual), DEF is the set of those that are defined (or defined with 
nondefault values, ideally), extracted from target headers and USE is the 
set of all identifiers used in the compiler that might possibly be macros 
(this generates much too big a set and in some cases should include those 
used in target headers, in some cases shouldn't; it also needs to cover 
#ifdef / #ifndef), then:

* Anything in DOC should be in DEF intersect USE.

* Anything in DEF intersect USE should be in DOC.

* Anything in DEF should be in the bigger version of USE (including uses 
within that target directory).

* Anything in USE that is used _as a macro_ (meaning in preprocessor
conditional tests) should be in a bigger version of DEF that includes
defines outside target headers and autoconf-generated defines.

A lot of such checks may generate false positives in practice.  But
perhaps robust scripts to generate DOC, the two versions of DEF and the
three versions of USE would help people do these tests.

I've decided to clear the target milestone for this PR.

Realistically, this bug just isn't ever going to hold up any release, ever.

So an undocumented macro has become an undocumented target hook; PR 3386
(still a regression) still applies.

Even though Mark cleared it but it would be nice to have it on People's radars for 3.5.
