Fix overflow in ipa_profile_generate_summary 2025-09-30T11:09:46+00:00 Jan Hubicka hubicka@ucw.cz 2025-09-30T11:07:53+00:00 69ac957ea56ad4b98baa8a6ca52ad0729b3358e0 With profile count scaling we now get overflow in ipa_profile_generate_summary which uses old macro GCOV_COMPUTE_SCALE that is not ready for very large counts. This patch replaces remaining two uses of it by (somewhat elaborate) profile-count based equivalent which is overflow safe. gcc/ChangeLog: * basic-block.h (GCOV_COMPUTE_SCALE): Remove. * ipa-profile.cc (ipa_profile_generate_summary): Use profile-count scaling. * sched-rgn.cc (compute_trg_info): Likewise. 
With profile count scaling we now get overflow in ipa_profile_generate_summary
which uses old macro GCOV_COMPUTE_SCALE that is not ready for very large
counts.  This patch replaces remaining two uses of it by (somewhat elaborate)
profile-count based equivalent which is overflow safe.

gcc/ChangeLog:

	* basic-block.h (GCOV_COMPUTE_SCALE): Remove.
	* ipa-profile.cc (ipa_profile_generate_summary): Use
	profile-count scaling.
	* sched-rgn.cc (compute_trg_info): Likewise.

gcc: Remove trailing whitespace

I've tried to build stage3 with
-Wleading-whitespace=blanks -Wtrailing-whitespace=blank -Wno-error=leading-whitespace=blanks -Wno-error=trailing-whitespace=blank
added to STRICT_WARN and that expectably resulted in about
2744 unique trailing whitespace warnings and 124837 leading whitespace
warnings when excluding *.md files (which obviously is in big part a
generator issue).  Others from that are generator related, I think those
need to be solved later.

The following patch just fixes up the easy case (trailing whitespace),
which could be easily automated:
for i in `find . -name \*.h -o -name \*.cc -o -name \*.c | xargs grep -l '[ 	]$' | grep -v testsuite/`; do sed -i -e 's/[ 	]*$//' $i; done
I've excluded files which I knew are obviously generated or go FE.

Is there anything else we'd want to avoid the changes?

Due to patch size, I've split it between gcc/ part (this patch)
and rest (include/, libiberty/, libgcc/, libcpp/, libstdc++-v3/).

I've tried to build stage3 with
-Wleading-whitespace=blanks -Wtrailing-whitespace=blank -Wno-error=leading-whitespace=blanks -Wno-error=trailing-whitespace=blank
added to STRICT_WARN and that expectably resulted in about
2744 unique trailing whitespace warnings and 124837 leading whitespace
warnings when excluding *.md files (which obviously is in big part a
generator issue).  Others from that are generator related, I think those
need to be solved later.

The following patch just fixes up the easy case (trailing whitespace),
which could be easily automated:
for i in `find . -name \*.h -o -name \*.cc -o -name \*.c | xargs grep -l '[ 	]$' | grep -v testsuite/`; do sed -i -e 's/[ 	]*$//' $i; done
I've excluded files which I knew are obviously generated or go FE.

Is there anything else we'd want to avoid the changes?

Due to patch size, I've split it between gcc/ part (this patch)
and rest (include/, libiberty/, libgcc/, libcpp/, libstdc++-v3/).

While working on PR117028 C2Y changes, I've noticed weird ternary
operator formatting (operand1 ? operand2: operand3).
The usual formatting is operand1 ? operand2 : operand3
where we have around 18000+ cases of that (counting only what fits
on one line) and
indent -nbad -bap -nbc -bbo -bl -bli2 -bls -ncdb -nce -cp1 -cs -di2 -ndj \
       -nfc1 -nfca -hnl -i2 -ip5 -lp -pcs -psl -nsc -nsob
documented in
https://www.gnu.org/prep/standards/html_node/Formatting.html#Formatting
does the same.
Some code was even trying to save space as much as possible and used
operand1?operand2:operand3 or
operand1 ? operand2:operand3

Today I've grepped for such cases (the grep was '?.*[^ ]:' and I had to
skim through various false positives with that where the : matched e.g.
stuff inside of strings, or *.md pattern macros or :: scope) and the
following patch is a fix for what I found.

don't declare header-defined functions both static and inline

Many functions defined in our headers are declared 'static inline' which
is a C idiom whose use predates our move to C++ as the implementation
language.  But in C++ the inline keyword is more than just a compiler
hint, and is sufficient to give the function the intended semantics.
In fact declaring a function both static and inline is a pessimization
since static effectively disables the desired definition merging
behavior enabled by inline, and is also a source of (harmless) ODR
violations when a static inline function gets called from a non-static
inline one (such as tree_operand_check calling tree_operand_length).

This patch mechanically fixes the vast majority of occurrences of this
anti-pattern throughout the compiler's headers via the command line

  sed -i 's/^static inline/inline/g' gcc/*.h gcc/*/*.h

There's also a manual change to remove the redundant declarations
of is_ivar and lookup_category in gcc/objc/objc-act.cc which would
otherwise conflict with their modified definitions in objc-act.h
(due to the difference in staticness).

Besides fixing some ODR violations, this speeds up stage1 cc1plus by
about 2% and reduces the size of its text segment by 1.5MB.

Add instruction level discriminator support.

This is the first in a series of patches to enable discriminator support
in AutoFDO.

This patch switches to tracking discriminators per statement/instruction
instead of per basic block. Tracking per basic block was problematic since
not all statements in a basic block needed a discriminator and, also, later
optimizations could move statements between basic blocks making correlation
during AutoFDO compilation unreliable. Tracking per statement also allows
us to assign different discriminators to multiple function calls in the same
basic block. A subsequent patch will add that support.

The idea of this patch is based on commit 4c311d95cf6d9519c3c20f641cc77af7df491fdf
by Dehao Chen in vendors/google/heads/gcc-4_8 but uses a slightly different
approach. In Dehao's work special (normally unused) location ids and side tables
were used to keep track of locations with discriminators. Things have changed
since then and I don't think we have unused location ids anymore. Instead,
I made discriminators a part of ad-hoc locations.

The difference from Dehao's work also includes support for discriminator
reading/writing in lto streaming and in modules.

Tested on x86_64-pc-linux-gnu.
