From: Ján Tomko Date: Sat, 14 Dec 2019 21:26:26 +0000 (+0100) Subject: build: relax the relaxed stack frame limit further X-Git-Tag: v6.0.0-rc1~232 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b87cca75c3b513cd3e62b68914a7abdb16c40bed;p=thirdparty%2Flibvirt.git build: relax the relaxed stack frame limit further Pick 256k as the limit. While -Wno-frame-larger-than would make more sense for usage in our test suite, the -Wno version seems to have no effect if -Wframe-larger-than was already specified. Use an (un)reasonably large value instead. Fixes the build with clang: ../../tests/cputest.c:964:1: error: stack frame size of 33176 bytes in function 'mymain' [-Werror,-Wframe-larger-than=] mymain(void) ^ 1 error generated.
