- * Work around GCC bug causing crashes in Mozilla with SSE2
- *
- * When using SSE2 intrinsics, gcc assumes that the stack is 16 byte
- * aligned. Unfortunately some code, such as Mozilla and Mono contain
- * code that aligns the stack to 4 bytes.
- *
- * The __force_align_arg_pointer__ makes gcc generate a prologue that
- * realigns the stack pointer to 16 bytes.
- *
- * On x86-64 this is not necessary because the standard ABI already
- * calls for a 16 byte aligned stack.
- *
- * See https://bugs.freedesktop.org/show_bug.cgi?id=15693
