Also add a scan for an mla\ninstruction.\n\nThe `ld1r` was needed when this should have generated\na mla by vector. Now that we can generate an mla by\nelement instruction and can load directly into the\nsimd register, it is cheaper to not do the ld1r\nwhich needlessly duplicates the single element used\nacross the whole vector register.\n\nThe testcase passes now that \nhttps://gcc.gnu.org/ml/gcc-patches/2017-08/msg00048.html has been committed\n\nOK for trunk?\n\nJackson\n\nChangeLog:\ngcc/testsuite\n\n2017-09-13 Jackson Woodruff \n\n\t* gcc.target/aarch64/pr62178.c: Updated testcase\n\tto scan for two ldrs and an mla.","diff":"diff --git a/gcc/testsuite/gcc.target/aarch64/pr62178.c b/gcc/testsuite/gcc.target/aarch64/pr62178.c\nindex b80ce68656076864bb71c76949cef5d7b530021a..1bf6d838d3a49ed5d8ecf9ae0157bd2a9159bfb4 100644\n--- a/gcc/testsuite/gcc.target/aarch64/pr62178.c\n+++ b/gcc/testsuite/gcc.target/aarch64/pr62178.c\n@@ -14,4 +14,6 @@ void foo (void) {\n }\n }\n \n-/* { dg-final { scan-assembler \"ld1r\\\\t\\{v\\[0-9\\]+\\.\"} } */\n+/* { dg-final { scan-assembler \"ldr\\\\ts\\[0-9\\]+, \\\\\\[x\\[0-9\\]+, \\[0-9\\]+\\\\\\]!\" } } */\n+/* { dg-final { scan-assembler \"ldr\\\\tq\\[0-9\\]+, \\\\\\[x\\[0-9\\]+\\\\\\], \\[0-9\\]+\" } } */\n+/* { dg-final { scan-assembler \"mla\\\\tv\\[0-9\\]+\\.4s, v\\[0-9\\]+\\.4s, v\\[0-9\\]+\\.s\\\\\\[0\\\\\\]\" } } */\n","prefixes":["Aarch64"]}
