--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
It seems to be make looking for all.c via the LTRANS makefile and us
invoking make -f /tmp/ccfGbAMc.mk -j2 all
/tmp/cczwBPXD.ltrans0.ltrans.o:
@gcc-8 '-xlto' '-c' '-fno-openmp' '-fno-openacc' '-mtune=generic'
'-march=x86-64' '-fPIC' '-shared' '-fPIC' '-v' '-save-temps' '-mtune=generic'
'-march=x86-64' '-fltrans-output-list=/tmp/cczwBPXD.ltrans.out' '-fltrans' '-o'
'/tmp/cczwBPXD.ltrans0.ltrans.o' '/tmp/cczwBPXD.ltrans0.o'
all: \
/tmp/cczwBPXD.ltrans0.ltrans.o
which eventually leads to
4924 execve("/usr/bin/cc", ["cc", "all.c", "/tmp/cczwBPXD.ltrans0.ltrans.o",
"-o", "all"], [/* 107 vars */]) = 0
if you make all.c invalid C then you see
> gcc-8 -shared -fPIC -flto=2 -x c t.c
all.c:1:1: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ at end of
input
invalid
^~~~~~~
make: *** [all] Error 1
lto-wrapper: fatal error: make returned 2 exit status
compilation terminated.
