Bug ID: 31824
Summary: gcc 14 fails during link step on Windows when
bootstrap-lto is specified
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: tanksherman27 at gmail dot com
Target Milestone: ---
gcc 14 seems to be unable to link itself when the bootstrap config that is
active is bootstrap-lto, to turn on Link Time Optimization for the gcc being
compiled. The following is the configure command:
# https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105507#c3
# At least with mingw32 + dwarf-2 exceptions there can only be one libgcc in
# process, or exceptions will no longer work. Since some of the gcc deps are
# linked dynamically like gmp/zlib/zstd and those pull in libgcc we can't
# allow libgcc to be linked statically. The default is "-static-libstdc++
# -static-libgcc" for both, so we drop "-static-libgcc" here:
# GCC 14 Update: Since we dropped 32bit Ada with GCC 14.1 and GCC doesn't use
# exceptions elsewhere this could in theory be removed, in case it makes
problems.
_extra_config+=(
'--with-boot-ldflags="-static-libstdc++"'
'--with-stage1-ldflags="-static-libstdc++"'
)
# In addition adaint.c does `#include <accctrl.h>` which pulls in msxml.h,
hacky hack:
CPPFLAGS+=" -DCOM_NO_WINDOWS_H"
