Is there reason to prevent the inlining once instrumentation is done?
No ;)
I think you can just block it for early inliner.
Sure. Do you have a handy predicate function that tells if einliner is done?
Thanks,

Hello.
I've just made a first version of the patchset that sits in GCC source tree:

Hello.
Similarly to e.g. sanitizer attributes, we sould prevent inlining when one
function
is marked as not instrumented. We should do that with -fprofile-generate only.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,

The current RTX pattern for BSR allows combine pass to convert LZCNT insn
to BSR. Note that the LZCNT has a defined behavior to return the operand
size when operand is zero, where BSR has not.
Add a BSR specific setting of zero-flag to RTX pattern of BSR insn

We were ignoring DR_STEP for VF == 1 which is OK only in case
the scalar order is preserved or both DR steps are the same.

Hi,
This patch adds an entry for cscope.out in .gitignore.
OK to commit ?
Sure.
Note that clangd provides much better support than legacy C cscope.

Hi,
when the assembler supports it, the compiler automatically passes --gdwarf-5
to it, which has an interesting side effect: any assembly instruction prior
to the first .file directive defines a new line associated with .file 0 in
the .debug_line section and, of course, the numbering of these imp

Hi all,
this patch updates OpenMP for the non-bug-fix commits which have
been done in the last weeks.
It also updates GCN. The change assumes that the just approved
patch is committed ...
Comments, thoughts, wording suggestions? Did I miss some commit/feature?

The issues are that 1) they use readelf instead of objdump and 2) they use
ELF syntax in the assembly code.
Tested on x86-64/Linux and x86[-64]/Windows, OK for mainline and 11 branch?
