2021-01-23add LTO supportAndrew Kelley
The CLI gains -flto and -fno-lto options to override the default. However, the cool thing about this is that the defaults are great! In general when you use build-exe in release mode, Zig will enable LTO if it would work and it would help. zig cc supports detecting and honoring the -flto and -fno-lto flags as well. The linkWithLld functions are improved to all be the same with regards to copying the artifact instead of trying to pass single objects through LLD with -r. There is possibly a future improvement here as well; see the respective TODOs. stage1 is updated to support outputting LLVM bitcode instead of machine code when lto is enabled. This allows LLVM to optimize across the Zig and C/C++ code boundary. closes #2845

2020-12-24stage2: fix Cache deadlock and build more of TSANAndrew Kelley
* rename is_compiler_rt_or_libc to skip_linker_dependencies and set it to `true` for all sub-Compilations. I believe this resolves the deadlock we were experiencing on Drone CI and on some users' computers. I will remove the CI workaround in a follow-up commit. * enabling TSAN automatically causes the Compilation to link against libc++ even if not requested, because TSAN depends on libc++. * add -fno-rtti flags where appropriate when building TSAN objects. Thanks Firefox317 for pointing this out. * TSAN support: resolve all the undefined symbols. We are still seeing a dependency on __gcc_personality_v0 but will resolve this one in a follow-up commit. * static libs do not try to build libc++ or libc++abi.

2020-12-08stage2: link: properly implement passthrough mode for LLD child procAndrew Kelley
passthrough mode does not mean always exit - it just means to pass through stdio and exit if the child process exits, without doing any special error reporting.

Closes #3825
2020-11-30fix regression on wasm targetsAndrew Kelley
The previous commit broke wasm targets because the linking step would look for the compiler-rt lib in the wrong place. Fixed in this commit.
2020-11-19stage2: Make zig cc more verbose (#7166)LemonBoy
* stage2: Make zig cc more verbose Make `zig cc` print more info from Clang itself and from our own linker invocation, this is needed for CMake to properly discover all the include directories and library search paths. Closes #7110 * Update `update_clang_options` * Typo fixes Co-authored-by: Jakub Konka <kubkon@jakubkonka.com>
2020-11-16Move leb128 and remove trivial *mem functions as discussed in #5588 (#6876)tgschultz
* Move leb128 out of debug and remove trivial *mem functions as discussed in #5588 * Turns out one of the *Mem functions was used by MachO. Replaced with trivial use of FixedBufferStream.
2020-10-09fixups to previous commitAndrew Kelley
* std.fs.Dir.readFile: add doc comments to explain what it means when the returned slice has the same length as the supplied buffer. * introduce readSmallFile / writeSmallFile to abstract over the decision to use symlink or file contents to store data.
