Subject: [committed] C-SKY: Add conditions for ceil etc patterns.
Date: Fri, 13 Jan 2023 20:38:05 +0800 [thread overview]
Message-ID: <20230113123805.75201-1-cooper.qu@linux.alibaba.com> (raw)
The ceil etc functions can be only inlined as instruction when
they can raise the "inexact" exception. Without the adding
conditions, it will cause the "gcc.dg/torture/builtin-fp-int-inexact-c2x.c"
etc cases fails.
gcc/
* config/csky/csky_insn_fpuv3.md (l<frm_pattern><fixsuop><mode>si2): Test
flag_fp_int_builtin_inexact || !flag_trapping_math.
(<frm_pattern><mode>2): Likewise.
