Bug ID: 115679
Summary: inlining failed in call to 'foo': function not
considered for inlining
Product: gcc
Version: 14.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: Changqing.Li at windriver dot com
Target Milestone: ---
The issue I met is similar to
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54965.
Reproduce steps:
1. wget https://cairographics.org/releases/pixman-0.43.4.tar.gz
2. Untar source
3. cd pixman-0.43.4; mkdir build;
4. add options -Og and -save-temps in meson.build
5. meson setup ./build
6. ninja -C ./build/
gcc version: both 14.0.1 and 14.1.0 can reproduce
system type: linux (eg: fedora 40)
Success option:
ARGS = -Ipixman/libpixman-1.so.0.43.4.p -Ipixman -I../pixman
-fdiagnostics-color=always -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch
-std=gnu99 -O2 -g -Wdeclaration-after-statement -fno-strict-aliasing
-fvisibility=hidden -Wundef -ftrapping-math -Wno-unused-local-typedefs
-DHAVE_CONFIG_H -fPIC -pthread
Fail option:
ARGS = -Ipixman/libpixman-1.so.0.43.4.p -Ipixman -I../pixman
-fdiagnostics-color=always -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch
-std=gnu99 -O2 -g -Wdeclaration-after-statement -fno-strict-aliasing
-fvisibility=hidden -Wundef -ftrapping-math -Og -Wno-unused-local-typedefs
-DHAVE_CONFIG_H -fPIC -pthread
Difference of success/fail option: -Og, once -Og is used, compile will fail.
Fail message:
