Lu hjl.tools at gmail dot com changed: What|Removed |Added Status|UNCONFIRMED |NEW Last reconfirmed||2015-08-09 CC||hjl.tools at gmail dot com Ever confirmed|0 |1 --- Comment #1 from H.J. Lu hjl.tools at gmail dot com --- Both ld and gold on binutils master branch support --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] to compress debug sections. --compress-debug-sections=zlib-gnu is for legacy .zdebug* compressed debug section support. Support for the gABI SHF_COMPRESSED debug sections should be sufficient. bfd, readelf and gold can decompress the SHF_COMPRESSED debug sections.
