--- Comment #8 from Mikael Pettersson <mikpe at it dot uu.se> 2011-06-24 09:59:58 UTC --- I've now bootstrapped and regtested the patch in #c5 on top of gcc-4.6-20110610 on an armv5tel-linux-gnueabi machine. (I couldn't get it to apply to trunk.) There were no build problems, it solved the test case, but there were a few testsuite regressions: +FAIL: gcc.dg/vect/nodump-pr23073.c (internal compiler error) +FAIL: gcc.dg/vect/nodump-pr23073.c (test for excess errors) /mnt/scratch/gcc-4.6-20110610/gcc/testsuite/gcc.dg/vect/nodump-pr23073.c: In function 'C': /mnt/scratch/gcc-4.6-20110610/gcc/testsuite/gcc.dg/vect/nodump-pr23073.c:19:1: error: unrecognizable insn: (insn 7 6 8 3 (set (mem/s/c:BLK (reg/f:SI 134) [3 d+0 S16 A32]) (unspec:V2SI [ (reg:V2SI 135) ] 205)) /mnt/scratch/gcc-4.6-20110610/gcc/testsuite/gcc.dg/vect/nodump-pr23073.c:16 -1 (nil)) /mnt/scratch/gcc-4.6-20110610/gcc/testsuite/gcc.dg/vect/nodump-pr23073.c:19:1: internal compiler error: in extract_insn, at recog.c:2109 +FAIL: gcc.dg/vect/vect-34.c (internal compiler error) +FAIL: gcc.dg/vect/vect-34.c (test for excess errors) /mnt/scratch/gcc-4.6-20110610/gcc/testsuite/gcc.dg/vect/vect-34.c: In function 'main1': /mnt/scratch/gcc-4.6-20110610/gcc/testsuite/gcc.dg/vect/vect-34.c:31:1: error: unrecognizable insn: (insn 41 40 42 3 (set (mem/s/c:BLK (reg/f:SI 173) [3 s+0 S16 A32]) (unspec:V8QI [ (reg:V8QI 175) ] 205)) /mnt/scratch/gcc-4.6-20110610/gcc/testsuite/gcc.dg/vect/vect-34.c:20 -1 (nil)) /mnt/scratch/gcc-4.6-20110610/gcc/testsuite/gcc.dg/vect/vect-34.c:31:1: internal compiler error: in extract_insn, at recog.c:2109 +FAIL: gcc.dg/vect/bb-slp-10.c (internal compiler error) +FAIL: gcc.dg/vect/bb-slp-10.c (test for excess errors) /mnt/scratch/gcc-4.6-20110610/gcc/testsuite/gcc.dg/vect/bb-slp-10.c: In function 'main1': /mnt/scratch/gcc-4.6-20110610/gcc/testsuite/gcc.dg/vect/bb-slp-10.c:41:1: error: unrecognizable insn: (insn 24 23 25 3 (set (mem/s/c:BLK (reg/f:SI 168) [2 out+0 S64 A64]) (unspec:V2SI [ (reg:V2SI 174) ] 205)) /mnt/scratch/gcc-4.6-20110610/gcc/testsuite/gcc.dg/vect/bb-slp-10.c:28 -1 (nil)) /mnt/scratch/gcc-4.6-20110610/gcc/testsuite/gcc.dg/vect/bb-slp-10.c:41:1: internal compiler error: in extract_insn, at recog.c:2109 +FAIL: gcc.target/arm/frame-pointer-1.c execution test The runtime test in foo() fails because p4 is 0xdeadbeef rather than 4.
