Created attachment 59013 [details] Patch to fix this bug Now that the initial (stage 1) POWER7 support patch has been accepted (see bug # 267630), I checked out the code from svn and tried to build it on a POWER7 system. The config test for VSX failed with the following error: configure:7307: gcc -c -mvsx conftest.c >&5 conftest.c: In function 'main': conftest.c:38:3: error: invalid 'asm': operand number missing after %-letter conftest.c:38:3: error: invalid 'asm': operand number missing after %-letter conftest.c:38:3: error: invalid 'asm': operand number missing after %-letter The line in configure.in that it's complaining about is: __asm__ __volatile__("xsmaddadp %vs32, %vs32, %vs33" ::: "memory","cc"); The "%" should not be included, and we'd also need to add " -Wa,-regnames" to the compile line. I'll attach a patch with this change, but alternatively, the line could simply be replaced with: __asm__ __volatile__("xsmaddadp 32, 32, 33" ::: "memory","cc");
> __asm__ __volatile__("xsmaddadp 32, 32, 33" ::: "memory","cc"); I committed this as r11699. Yell if it still doesn't work.
