re PR target/83994 (%ebx is clobbered by stack-clash probing for regparm-3 function in PIC mode)
PR target/83994
* i386.c (get_probe_interval): Move to earlier point.
(ix86_compute_frame_layout): If -fstack-clash-protection and
the frame is larger than the probe interval, then use pushes
to save registers rather than reg->mem moves.
(ix86_expand_prologue): Remove conditional for int_registers_saved
assertion.
PR target/83994
* gcc.target/i386/pr83994.c: New test.
