Hi, This patch modifies gcc.dg/vect/slp-reduc-15.c to add aarch64 support with -march=armv8.2-a+sve and restricts the test to x86_64 and aarch64 only.
Tested on aarch64 and x86_64. OK for trunk? Thanks, Lili The test uses __GIMPLE with .COND_ADD internal function, which requires architecture-specific options to enable masked/conditional vector operations. The test was previously x86_64-only, causing failures on aarch64. This patch adds aarch64 support with -march=armv8.2-a+sve for SVE, and restricts the test to only run on x86_64 and aarch64 platforms where we provide the appropriate -march options. On other platforms (RISC-V, PowerPC, etc.), the test is skipped.
