The patch below implements part of this. Unlike gcc.dg/torture/stackalign/stackalign.exp, I'm using the code below to add -fpic etc. to the torture options so it shows up in gcc.sum. Unfortunately, I have no idea how to properly test if -fpie/-fPIE is supported. Jakub, do you have a suggestion? Such a test could (and probably should) be used in the few tests we currently have for -fpie: gcc.dg/tls/pie-1.c, gcc.dg/pie-link.c, gcc.target/i386/pr39013-[12].c Bootstrapped without regression on i386-pc-solaris2.11. Will install on mainline unless someone objects once the -fpie test has been fixed.
