several cases, here’s the most modern with an m32 multilib: Configured with: /src-local/gcc-git-9/configure --prefix=/opt/iains/x86_64-apple-darwin17/gcc-9-wip --build=x86_64-apple-darwin17 --with-sysroot=/Library//Developer/CommandLineTools/SDKs/MacOSX.sdk --with-as=/XC/9.4/usr/bin/as --with-ld=/XC/9.4/usr/bin/ld --enable-languages=all CC=x86_64-apple-darwin17-gcc CXX=x86_64-apple-darwin17-g++ log info: [ note the m64 multilib, also emits the diagnostic, but it does not appear to spin. ] /scratch/10-13-his/gcc-9-wip/gcc/xgcc -B/scratch/10-13-his/gcc-9-wip/gcc/ /src-local/gcc-git-9/gcc/testsuite/gcc.target/i386/pr88414.c -m32 -fno-diagnostics-show-caret -fno-diagnostics-show-line-numbers -fdiagnostics-color=never -O1 -ftrapv -S -o pr88414.s /src-local/gcc-git-9/gcc/testsuite/gcc.target/i386/pr88414.c: In function 'foo': /src-local/gcc-git-9/gcc/testsuite/gcc.target/i386/pr88414.c:15:7: error: 'asm' operand has impossible constraints got a INT signal, interrupted by user // (manually killed it) Iain
