On linux I see eight in fold-vec-insert-int-p9.c tearing down the stack frame in function epilogues, and four in addi 9,1,16 lvewx 0,0,9 For aix you have the above four but with a -16 offset. There are no stack frames, and you have four addressing stack red-zone as addi 9,1,-64 fold-vec-extract-char.p9.c on linux just has epilogue addi, aix has red-zone addressing. The same for fold-vec-extract-int.p9.c, fold-vec-extract-longlong.p7.c and fold-vec-extract-longlong.p8.c. It seems silly to count addi in a function epilogue, and fragile to count them in code. So remove the ilp32 addi checks. * gcc.target/powerpc/fold-vec-extract-char.p9.c: Don't check addi count for ilp32. * gcc.target/powerpc/fold-vec-extract-int.p9.c: Likewise. * gcc.target/powerpc/fold-vec-extract-longlong.p7.c: Likewise. * gcc.target/powerpc/fold-vec-extract-longlong.p8.c: Likewise. * gcc.target/powerpc/fold-vec-insert-int-p9.c: Likewise. --- diff --git a/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-char.p9.c b/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-char.p9.c index ff03c9a722b..8a4c380edad 100644 --- a/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-char.p9.c +++ b/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-char.p9.c @@ -12,7 +12,6 @@ /* { dg-final { scan-assembler-times "stxv" 6 { target ilp32 } } } */ /* { dg-final { scan-assembler-times "lbz" 6 { target ilp32 } } } */ -/* { dg-final { scan-assembler-times "addi" 3 { target ilp32 } } } */ #include diff --git a/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-int.p9.c b/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-int.p9.c index 868b673cdaf..1abf19da40d 100644 --- a/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-int.p9.c +++ b/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-int.p9.c @@ -18,7 +18,6 @@ /* { dg-final { scan-assembler-times {\madd\M} 3 { target ilp32 } } } */ /* { dg-final { scan-assembler-times {\mstxv\M} 6 { target ilp32 } } } */ /* { dg-final { scan-assembler-times {\mlwz\M} 6 { target ilp32 } } } */ -/* { dg-final { scan-assembler-times {\maddi\M} 3 { target ilp32 } } } */ #include diff --git a/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-longlong.p7.c b/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-longlong.p7.c index 033d21c9a43..b97fcb40eda 100644 --- a/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-longlong.p7.c +++ b/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-longlong.p7.c @@ -22,7 +22,6 @@ /* -m32 target with constant test uses (+2)li where the -m64 has an ld */ /* { dg-final { scan-assembler-times {\mli\M} 5 { target ilp32 } } } */ /* { dg-final { scan-assembler-times {\maddi\M} 6 { target lp64 } } } */ -/* { dg-final { scan-assembler-times {\maddi\M} 4 { target ilp32 } } } */ /* { dg-final { scan-assembler-times {\mstxvd2x\M|\mstvx\M} 3 } } */ /* { dg-final { scan-assembler-times {\mrldic\M|\mrlwinm\M} 3 } } */ /* { dg-final { scan-assembler-times {\mldx\M} 3 { target lp64 } } } */ diff --git a/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-longlong.p8.c b/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-longlong.p8.c index 0b624d262e1..8ddce3fd2d8 100644 --- a/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-longlong.p8.c +++ b/gcc/testsuite/gcc.target/powerpc/fold-vec-extract-longlong.p8.c @@ -17,7 +17,6 @@ /* { dg-final { scan-assembler-times {\mstxvd2x\M|\mstxvw4x\M} 4 { target ilp32 } } } */ /* { dg-final { scan-assembler-times {\madd\M} 3 { target ilp32 } } } */ /* { dg-final { scan-assembler-times {\mlwz\M} 11 { target ilp32 } } } */ -/* { dg-final { scan-assembler-times {\maddi\M} 4 { target ilp32 } } } */ /* { dg-final { scan-assembler-times {\mmfvsrd\M} 6 { target lp64 } } } */ /* { dg-final { scan-assembler-times {\mmtvsrd\M} 3 { target lp64 } } } */ /* { dg-final { scan-assembler-times {\mxxpermdi\M} 3 { target le } } } */ diff --git a/gcc/testsuite/gcc.target/powerpc/fold-vec-insert-int-p9.c b/gcc/testsuite/gcc.target/powerpc/fold-vec-insert-int-p9.c index 81ac1f1a00a..a851fd6b8dc 100644 --- a/gcc/testsuite/gcc.target/powerpc/fold-vec-insert-int-p9.c +++ b/gcc/testsuite/gcc.target/powerpc/fold-vec-insert-int-p9.c @@ -58,8 +58,6 @@ testui2_cst(unsigned int x, vector unsigned int v) /* { dg-final { scan-assembler-times {\mmtvsrwz\M} 4 { target lp64 } } } */ /* { dg-final { scan-assembler-times {\mxxinsertw\M} 4 { target lp64 } } } */ - -/* { dg-final { scan-assembler-times {\maddi\M} 8 { target ilp32 } } } */ /* { dg-final { scan-assembler-times {\mstw\M} 8 { target ilp32 } } } */ /* { dg-final { scan-assembler-times {\mlxv\M} 8 { target ilp32 } } } */ /* { dg-final { scan-assembler-times {\mlvewx\M} 4 { target ilp32 } } } */
