The opt-out from rL236267 (2015) is untested and seems no longer needed (or not
needed when rL236267 was committed): there is nothing special with uncompressed
alignment. This brings us in line with GCC which compresses .debug_frame .
Checked that -g -fno-asynchronous-unwind-tables + objcopy
--decompress-debug-sections output is identical to -g
-fno-asynchronous-unwind-tables -gz + objcopy --decompress-debug-sections
output.
auto &MC = Asm.getContext();
const auto &MAI = MC.getAsmInfo();
- // Compressing debug_frame requires handling alignment fragments which is
- // more work (possibly generalizing MCAssembler.cpp:writeFragment to allow
- // for writing to arbitrary buffers) for little benefit.
bool CompressionEnabled =
MAI->compressDebugSections() != DebugCompressionType::None;
- if (!CompressionEnabled || !SectionName.startswith(".debug_") ||
- SectionName == ".debug_frame") {
+ if (!CompressionEnabled || !SectionName.startswith(".debug_")) {
Asm.writeSectionData(W.OS, &Section, Layout);
return;
