[Testsuite] tree-ssa failures for targets with non 32 bit int size

I noticed that there is a bunch of testcases in gcc.dg/tree-ssa (slsr-27.c, for e.g.) that assume that the size of the integer is 4 bytes. For example, slsr-27.c has struct x { int a[16]; int b[16]; int c[16]; }; and void f (struct x *p, unsigned int n) { foo (p->a[n], p->c[n], p->b[n

good afternoon

Good afternoon. I need a function that it only works with my server. (Server lunix - panel DirectAdmin) I was told for it to write the language C + + module for PHP extension. So If so I want to buy one for ordering function (. so) format, which he eats at me like PHP format. (need to translate

ARM, stack unwinding, and Firefox OS

I've been working on profiling tools for Firefox OS, and one of the central problems is getting stack traces for sample-based profiling. The old APCS frame pointer variant (where r11/fp heads a linked list of {fp, sp, lr, pc} frames) is convenient -- it's compatible with the Linux kernel profiler a
