Testsuite resolves non-unique test names under several sections
This patch improves readability of GCC test reports by appending options to test names, making many previously non-unique test entries distinct.
The GCC testsuite’s compare_test utility highlighted a significant number of non-unique test names, reducing the clarity of test reports. This commit introduces modifications to modules.exp and lto.exp to append relevant compilation options (like C++ standard versions or LTO flags) to test names in the report. This change makes approximately 70-75% of previously ambiguous entries distinct, greatly improving the readability of regression test results by allowing more precise identification of individual test runs.
In Details
The compare_test utility for GCC's testsuite suffered from a proliferation of non-unique test names, especially within modules.exp and lto.exp. This issue obscured regression analysis. The patch appends key compiler options, such as -std=c++17 or specific LTO flags, to the test report's output for individual test runs. By making these previously identical entries unique, the readability and diagnostic utility of the test reports are significantly enhanced for toolchain developers, facilitating precise identification of regressions without having to manually deduce the specific compila…
For Context
When GCC runs its extensive suite of tests, it generates reports that show which tests passed or failed. However, many tests had the exact same name, even if they were run with different compiler settings (like different C++ language versions or Link-Time Optimization options). This made it very hard to tell apart individual test results in the report, especially when looking for errors. This change modifies the test reports to automatically include the specific compilation options used for each test run in its name. This makes each entry unique and much easier to read, helping developers quickly identify and fix problems when new changes cause tests to fail.
