commit 93ed472702aad6d9b8998592775a0ab4120b6242 Author: law Date: Wed Sep 20 21:59:50 2017 +0000 * explow.c (compute_stack_clash_protection_loop_data): Use CONST_INT_P instead of explicit test. Verify object is a CONST_INT_P before looking at INTVAL. (anti_adjust_stack_and_probe_stack_clash): Use CONST_INT_P instead of explicit test. * gcc.target/i386/stack-check-11.c: Update test and regexp so that it works for both i?86 and x86_64. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@253034 138bc75d-0d04-0410-961f-82ee72b054a4 diff --git a/gcc/explow.c b/gcc/explow.c index 2526e8513b7..d118e0d7782 100644 --- a/gcc/explow.c +++ b/gcc/explow.c @@ -1778,11 +1778,11 @@ compute_stack_clash_protection_loop_data (rtx *rounded_size, rtx *last_addr, if (*rounded_size == CONST0_RTX (Pmode)) fprintf (dump_file, "Stack clash skipped dynamic allocation and probing loop.\n"); - else if (GET_CODE (*rounded_size) == CONST_INT + else if (CONST_INT_P (*rounded_size) && INTVAL (*rounded_size) <= 4 * *probe_interval) fprintf (dump_file, "Stack clash dynamic allocation and probing inline.\n"); - else if (GET_CODE (*rounded_size) == CONST_INT) + else if (CONST_INT_P (*rounded_size)) fprintf (dump_file, "Stack clash dynamic allocation and probing in " "rotated loop.\n"); @@ -1880,7 +1880,8 @@ anti_adjust_stack_and_probe_stack_clash (rtx size) if (rounded_size != CONST0_RTX (Pmode)) { - if (INTVAL (rounded_size) <= 4 * probe_interval) + if (CONST_INT_P (rounded_size) + && INTVAL (rounded_size) <= 4 * probe_interval) { for (HOST_WIDE_INT i = 0; i < INTVAL (rounded_size); @@ -1900,7 +1901,7 @@ anti_adjust_stack_and_probe_stack_clash (rtx size) else { rtx loop_lab, end_loop; - bool rotate_loop = GET_CODE (rounded_size) == CONST_INT; + bool rotate_loop = CONST_INT_P (rounded_size); emit_stack_clash_protection_probe_loop_start (&loop_lab, &end_loop, last_addr, rotate_loop); @@ -1938,7 +1939,7 @@ anti_adjust_stack_and_probe_stack_clash (rtx size) might hold live data.
