Bug ID: 99973
Summary: -gsplit-dwarf uses host objcopy for cross compilers
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: rsandifo at gcc dot gnu.org
Target Milestone: ---
ASM_FINAL_SPEC has:
"%{gsplit-dwarf: \n\
objcopy --extract-dwo \
%{c:%{o*:%*}%{!o*:%w%b%O}}%{!c:%U%O} \
%b.dwo \n\
objcopy --strip-dwo \
%{c:%{o*:%*}%{!o*:%w%b%O}}%{!c:%U%O} \
}"
which hard-codes the assumption that a command called “objcopy”
will work for the target. This is true for native compilers but
isn't usually true for cross compilers.
This is causing:
FAIL: gcc.dg/lto/pr83719 c_lto_pr83719_0.o assemble, -flto -g -gsplit-dwarf
