4 | Subject: [PATCH] aarch64: fix check for SVE support in assembler | ||
5 | |||
6 | Due to GCC bug 110901 -mcpu can override -march setting when compiling | ||
7 | asm code and thus a compiler targetting a specific cpu can fail the | ||
8 | configure check even when binutils gas supports SVE. | ||
9 | |||
10 | The workaround is that explicit .arch directive overrides both -mcpu | ||
11 | and -march, and since that's what the actual SVE memcpy uses the | ||
12 | configure check should use that too even if the GCC issue is fixed | ||
13 | independently. | ||
14 | |||
