testsuite: Add AVX512 requirement to a vectorization test.
The test case vect-early-break-no-epilog_11.c now requires AVX512 instructions on x86_64 to vectorize correctly.
The test case vect-early-break-no-epilog_11.c now requires AVX512 instructions for vectorization on x86_64 architectures. Without AVX512, the test may not vectorize as intended. This change ensures that the test is only run on systems that support AVX512, preventing false negatives.
In Details
This commit modifies a test case in gcc.dg/vect/ to add an AVX512 requirement on x86_64. The test relies on AVX512 vector instructions for proper execution. Without AVX512, the vectorization may fail. This change affects the testsuite infrastructure and its interaction with the x86_64 target.
For Context
Compilers often include a suite of tests to ensure they are functioning correctly. These tests verify that the compiler can correctly translate source code into machine code, including optimizations such as vectorization. Vectorization is a technique that allows the compiler to perform the same operation on multiple data elements simultaneously, improving performance. This commit adds a requirement for AVX512 instructions to a specific vectorization test. AVX512 is a set of instructions that provides enhanced vector processing capabilities. This ensures that this particular test is only run on processors that support AVX512, preventing potential failures on older processors.
