2022-03-22lto-plugin: Use GNU ld or Solaris ld version script in preference to ↵Jakub Jelinek5-8/+179
-export-symbols-regex [PR102426] As reported, libtool -export-symbols-regex doesn't work on Solaris when using GNU ld instead of Sun ld, libtool just always assumes Sun ld. As I'm unsure what is the maintainance status of libtool right now, this patch solves it on the lto-plugin side instead, tests at configure time similar way how libssp and other target libraries test for symbol versioning (except omitting the symbol version because we just want one GLOBAL symbol and rest of them LOCAL), and will use the current way of -export-symbols-regex onload as fallback when this doesn't work. 2022-03-22 Jakub Jelinek <jakub@redhat.com> PR lto/102426 lto-plugin/ * configure.ac (LTO_PLUGIN_USE_SYMVER, LTO_PLUGIN_USE_SYMVER_GNU, LTO_PLUGIN_USE_SYMVER_SUN): New test for symbol versioning support. * Makefile.am (version_arg, version_dep): Set conditionally based on LTO_PLUGIN_USE_SYMVER*.

The transposition nolto -> notlo is confusing and it makes the long name even harder to read than it already is - I kept reading it as "not lo" until I realized it was a simple typo.

2021-06-25add -ltrans-objects lto-plugin debug optionRichard Biener1-0/+12
This adds a -ltrans-objects option to lto-plugin that by-passes lto-wrapper invocation and instead feeds LD the final LTRANS objects directly from the response file given as argument to the option. This allows LD issues involving the linker-plugin path to be debugged in an easier way with just the IR objects (their symtab) and the LTRANS objects as testcase. I've tested the path re-building stage2 build/genmatch from an LTO bootstrap and got a bit-identical executable by adding -plugin-opt=-ltrans-objects=y to the original collect2 invocation, seeding y with the final objects as printed by building genmatch with -save-temps -v. 2021-06-22 Richard Biener <rguenther@suse.de> lto-plugin/ * lto-plugin.c (ltrans_objects): New global. (all_symbols_read_handler): If -ltrans-objects was specified, add the output files from the specified file directly. (process_option): Handle -ltrans-objects.

2020-11-25libsanitizer: Add option to bootstrap using HWASANMatthew Malcomson2-4/+4
This is an analogous option to --bootstrap-asan to configure. It allows bootstrapping GCC using HWASAN.
