From add71b95dd27d73d64eee0a9c8f748672b7050f5 Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Fri, 13 Jan 2023 11:13:22 +0100 Subject: testsuite: Add testcase for PR that went latent in GCC 13 [PR107131] The following testcase is probably latent since r13-3217-gc4d15dddf6b9e. Adding testcase so that it doesn't silently reappear. 2023-01-13 Jakub Jelinek PR target/107131 * gcc.dg/pr107131.c: New test. --- gcc/testsuite/gcc.dg/pr107131.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr107131.c (limited to 'gcc') diff --git a/gcc/testsuite/gcc.dg/pr107131.c b/gcc/testsuite/gcc.dg/pr107131.c new file mode 100644 index 0000000..458b128 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr107131.c @@ -0,0 +1,30 @@ +/* PR target/107131 */ +/* { dg-do run } */ +/* { dg-options "-Os -fno-ipa-vrp -fno-tree-bit-ccp -Wno-psabi" } */ + +typedef unsigned char C; +typedef unsigned long long __attribute__((__vector_size__ (32))) U; +typedef unsigned long long __attribute__((__vector_size__ (64))) V; + +static __attribute__((__noclone__)) C +foo (C o, U x, U y, U z) +{ + V a = __builtin_shufflevector (x, x, 3, 1, 3, 0, 0, 1, 1, 3); + V b = (V) { } >= o; + V c = b <= (V)(b >= (V) { 0, 0, 0, 0, 0, 0x90DF0BE3990AC871ULL }); + U d = __builtin_shufflevector (y, z, 3, 1, 4, 5); + V e = a + c; + U f = ((union { V v; U u[2]; }) e).u[1] + d; + return ((union { U u; C c[32]; }) f).c[9]; +} + +int +main () +{ + if (__SIZEOF_LONG_LONG__ != 8 || __CHAR_BIT__ != 8) + return 0; + C x = foo (0, (U) { }, (U) { }, (U) { }); + if (x != 0xff) + __builtin_abort(); + return 0; +} -- cgit v1.1
