Hi,
The recent fix for PR94426 (g8d213cbbe1856e6088282aa0076646cec694b030)
causes regressions on arm:
g++.dg/lto/pr83720 cp_lto_pr83720_0.o assemble, -O0 -flto
-flto-partition=1to1 -fno-use-linker-plugin
g++.dg/lto/pr83720 cp_lto_pr83720_0.o assemble, -O0 -flto
-flto-partition=none -fuse-linker-plugin
g++.dg/lto/pr83720 cp_lto_pr83720_0.o assemble, -O0 -flto
-fuse-linker-plugin -fno-fat-lto-objects
g++.dg/lto/pr83720 cp_lto_pr83720_0.o assemble, -O2 -flto
-flto-partition=1to1 -fno-use-linker-plugin
g++.dg/lto/pr83720 cp_lto_pr83720_0.o assemble, -O2 -flto
-flto-partition=none -fuse-linker-plugin -fno-fat-lto-objects
g++.dg/lto/pr83720 cp_lto_pr83720_0.o assemble, -O2 -flto
-fuse-linker-plugin
The logs say:
/gcc/testsuite/g++.dg/lto/pr83720_0.C:51:18: warning: 'virtual
void<lambda(b::ai)>::be::f()' used but never defined
Does the testcase need an adjustment?
