AArch64 test vcond_18.c is updated for consistency
GCC's AArch64 test suite received an update to align the vcond_18.c test with current compiler behavior.
This commit updates the vcond_18.c test case within GCC’s AArch64 test suite. The changes bring the test up to date with expected output or behavior, ensuring it accurately verifies the compiler’s functionality for vector conditional operations on AArch64. This is a routine maintenance task to keep the test suite reliable and current.
In Details
This update pertains to the GCC testsuite for AArch64, specifically within the SVE (Scalable Vector Extension) portion. The vcond_18.c test likely exercises vector conditional instructions and predicates, which are critical for efficient vector programming on AArch64. The change implies either a desired change in generated assembly or an adjustment to the expected output due to other compiler changes, ensuring the ongoing correctness of the SVE implementation.
For Context
When you write code, a compiler translates it into instructions that a computer's processor can understand. Because processors vary, compilers have different 'backends' for each architecture, like AArch64. To ensure the compiler does its job correctly across these architectures, a comprehensive test suite exists, containing many small programs designed to test specific features. This commit updates one of those test programs, vcond_18.c, for the AArch64 architecture. This ensures that when the compiler is changed or updated, this test still correctly verifies that the compiler generates the right instructions for conditional operations used in vector programming, which is important for performance. This change helps maintain the quality and correctness of the compiler over time.
