Subject: [Bug target/35757] New: [4.4 Regression] Incorrect contraint on sse4_1_blendp<ssemodesuffixf2c>
Date: Sat, 29 Mar 2008 16:08:00 -0000 [thread overview]
Message-ID: <bug-35757-682@http.gcc.gnu.org/bugzilla/> (raw)
sse.md has
(define_insn "sse4_1_blendp<ssemodesuffixf2c>"
[(set (match_operand:SSEMODEF2P 0 "register_operand" "=x")
(vec_merge:SSEMODEF2P
(match_operand:SSEMODEF2P 2 "nonimmediate_operand" "xm")
(match_operand:SSEMODEF2P 1 "register_operand" "0")
(match_operand:SI 3 "const_0_to_3_operand" "n")))]
"TARGET_SSE4_1"
"blendp<ssemodesuffixf2c>\t{%3, %2, %0|%0, %2, %3}"
[(set_attr "type" "ssemov")
(set_attr "prefix_extra" "1")
(set_attr "mode" "<MODE>")])
The problem is blendpd takes 0 to 15 as immediate operand. The problem
is hidden in testsuite due to MAEK defined in sse4_1-check.h.
