Fix up compression related test cases Fallout from r205261, ensure it doesn't matter how we disable compressed debug info, even if zlib is missing and that we warn when we don't have zlib and don't warn when we do, all while silently suppressing these tests on the systems they weren't intended for... llvm-svn: 205271

// REQUIRES: zlib
Warn when requesting compress-debug-sections and zlib is not available Another shot in the dark, since I do have zlib installed. Will be watching the bots for fallout. llvm-svn: 205265

Revert "Revert r305164/5/7." Restore the `-gz` option to the driver with some minor tweaks to handle the additional case for `-Wa,--compress-debug-sections`. This intends to make the compression of the debug information controllable from the driver. The following is the behaviour: -gz enable compression (ambiguous for format, will default to zlib-gnu) -gz=none disable compression -gz=zlib-gnu enable compression (deprecated GNU style zlib compression) -gz=zlib enable compression (zlib based compression) Although -Wa,-compress-debug-sections works, it should be discouraged when using the driver to invoke the assembler. However, we permit the assembler to accept the GNU as style argument --compress-debug-sections to maintain compatibility. Note, -gz/-gz= does *NOT* imply -g. That is, you need to additionally specific -g for debug information to be generated. llvm-svn: 306115

[Driver] Clean up -gz & --compress-debug-sections * Make cc1 and cc1as --compress-debug-sections an alias for --compress-debug-sections=zlib * Make -gz an alias for -gz=zlib The new behavior is consistent with GCC when binutils>=2.26 is detected: -gz is translated to --compress-debug-sections=zlib instead of --compress-debug-sections.

Fix -gz=zlib options for linker gcc translates -gz=zlib to --compress-debug-options=zlib for both assembler and linker but clang only does this for assembler. The linker needs --compress-debug-options=zlib option to compress the debug sections in the generated executable or shared library. Due to this bug, -gz=zlib has no effect on the generated executable or shared library. This patch fixes that. Differential Revision: https://reviews.llvm.org/D87321

Fix a couple of tests that relied on the clang binary having 'clang' somewhere in the name Because why would that be necessary? (I joke - I hadn't actually expected this to be an issue but a content-hash-named filesystem means the clang binary's just a bunch of numbers, and doesn't have 'clang' anywhere in the name)
