Bug ID: 67156
Summary: config/bootstrap-debug.mk: STAGE2_CFLAGS += -gtoggle
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: dilyan.palauzov at aegee dot org
Target Milestone: ---
config/bootstrap-debug.mk contains:
STAGE2_CFLAGS += -gtoggle
and in turn stage2 is compiled with -gtoggle, while stage3 is compile without
-gtoggle. This can be seen by comparing stage{2,3}-gcc/Makefile . After
finishing stage3, the build process compares the binaries from stage2 and
stage3, which differ, because they were compiled with/out -gtoggle.
Removing -gtoggle from config/bootstrap-debug.mk:STAGE2_CFLAGS enables to
finish the compilation without errors (during the final comparison)
I compile gcc with
/git/gcc/configure --enable-host-shared --enable-threads=posix
--with-arch=haswell --enable-__cxa_atexit --enable-languages=c,c++,lto,jit
--enable-targets=all --enable-nls --with-linker-hash-style=gnu
--with-system-zlib --disable-multilib
and the gcc-git repository is at the newest state.
