This occurs both with and without -mcall-ms2sysv-xlogues. Additionally, the stack allocation with -mcall-ms2sysv-xlogues is ignoring (silently disabling) stack checking, stack clash checking and probing. This patch fixes these problems by: 1. No longer allocate stack space in ix86_emit_outlined_ms2sysv_save. 2. Rearrange where we emit SSE saves or stub call: a. Before frame allocation when offset from frame to save area is >= 2GiB. b. After frame allocation when frame is < 2GiB. (Stack allocations prior to the stub call can't be combined with those afterwards, so this is better when possible.) 3. Modify choose_baseaddr to take an optional scratch_regno argument and never return rtx that cannot be used as an immediate. gcc: config/i386/i386.c (choose_basereg): Use optional scratch register and add assertion. (x86_emit_outlined_ms2sysv_save): Use scratch register when needed, and don't allocate stack.
