> /usr/bin/ld: crtsavres.o: No such file: No such file or directory

andrew@ has disabled BSD_CRTBEGIN on powerpc in r341424
Comment 1 Mark Millard 2018-12-04 05:06:45 UTC
Why did https://ci.freebsd.org/job/FreeBSD-head-powerpc64-build/8288/
and https://ci.freebsd.org/job/FreeBSD-head-powerpc-build/8576/
(Nov 23) and various later not show failures from the change?

Had the builds been using old crtsavres.o files from prior builds?
(If so, such does not seem to be a good property of the build
environment.)

I wonder if it is a race condition instead of just-missing
file.

Looking at the build logs I see things like:

--- crtsavres.o ---
. . . 
--- crtsavres.o ---
cc --sysroot=/usr/obj/usr/src/powerpc.powerpc/tmp -B/usr/obj/usr/src/powerpc.powerpc/tmp/usr/bin -x assembler-with-cpp -O2 -pipe   -DIN_GCC -DHAVE_LD_EH_FRAME_HDR -DDT_CONFIG -D__GLIBC__=3 -fno-inline-functions -fno-exceptions  -fno-zero-initialized-in-bss -fno-asynchronous-unwind-tables  -fno-omit-frame-pointer -I/usr/src/contrib/gcclibs/include -I/usr/src/contrib/gcc/config -I/usr/src/contrib/gcc -I.  -I/usr/src/gnu/usr.bin/cc/cc_tools -g  -std=gnu89    -finhibit-size-directive -fno-toplevel-reorder    -c /usr/src/contrib/gcc/config/rs6000/crtsavres.asm  -o crtsavres.o

and:

This may be a duplicate of bugzilla 233733 .

(In reply to Mark Millard from comment #3)
There is a race condition as well but this PR is not a duplicate -- once PR233733 is fixed powerpc with BSD_CRTBEGIN should consistently fail due to missing crtsavres.o.
