The selftests currently assume both: (a) reading a source file from /dev/null, and (b) writing the generated asm to /dev/null I note that r241895 added "-o /dev/null" for the asm output to "Fix the Windows native x86-64 build.": +2016-11-07 Tamar Christina <tamar.christ...@arm.com> + + PR driver/78196 + * Makefile.in (SELFTEST_FLAGS): Added -o /dev/null. + HOST_BIT_BUCKET seems to be a header thing, rather than a Makefile thing; presumably there would need to be logic to handle both input and output for the HOST_BIT_BUCKET approach. Given that, I prefer Olivier's patch - it seems simpler to me. Dave
