2021-04-09llvm new-pm: Build O0 pipeline in the correct wayMin-Yih Hsu
Use `PassBuilder::buildO0DefaultPipeline` to build pipeline for -O0 in replacement of `PassBuilder::buildPerModuleDefaultPipeline`. This affects both normal and LTO settings. Two redundant Passes - which were added by accident - were also removed from LTO pipeline.
2021-04-09Revert "Revert back to the old LLVM PassManager"Min-Yih Hsu
This reverts commit 09008125e7944ae01bb907f2eb8dbff41d7a0715.
2021-04-06stage1: Work around a small problem in LLVM APILemonBoy
The missing initializer for a single field in the TargetOptions class was enough to turn the stack protectors into hot garbage. Fixes #8408
2021-04-02Revert back to the old LLVM PassManagerAndrew Kelley
See #8418 This reverts commit ba1bea2fe87b73a53a3ecd729789853dcc56affe. This reverts commit 94383d14df77fa638dac14f4b2bda5a2e3f21c5c. This reverts commit 0d53a2bff01750f9220bcc861d662b2c5f304506.
2021-04-02zig_llvm.cpp: remove dead codeAndrew Kelley
2021-04-02llvm new-pm: Add missing pipeline option and PassesMin-Yih Hsu
- Enable MergeFunctionsPass in non-debug build. - Verify input and output IR when the assertion is turned on. - Add AlwaysInlinePass in debug build. - Add more comments.
2021-04-02llvm new-pm: Port LLVM 11.x-based changes to LLVM 12.xMin-Yih Hsu
Now zig will use new PM for optimization by default.
2021-02-28stage1: update to LLVM 12 sret callsite requirementsAndrew Kelley
Without this, the LLVM IR that zig generates cannot be compiled by LLVM.
2021-02-26stage1: Fix emission of sret annotation for LLVMLemonBoy
LLVM12 deprecated `sret` and replaced it with the `sret(<Ty>)` form. Closes #8075
2021-02-26Revert "stage1: upgrade to new LLVM sret attribute requirement"Andrew Kelley
This reverts commit 685b5c26b703d54381a74b71361816ad85ec8584. @LemonBoy has a better patch, so reverting this to merge that one.
2021-02-26stage1: upgrade to new LLVM sret attribute requirementAndrew Kelley
LLVM 12 requires sret attributes to have the struct type as a parameter, and provides no C function for supplying it. Therefore, we must add another C++ wrapper API for adding the sret attribute. Fixes ability to build from source in the llvm12 branch.
2021-02-25Merge remote-tracking branch 'origin/master' into llvm12Andrew Kelley
Conflicts: * src/clang.zig * src/llvm.zig - this file got moved to src/llvm/bindings.zig in master branch so I had to put the new LLVM arch/os enum tags into it. * lib/std/target.zig, src/stage1/target.cpp - haiku had an inconsistency with its default target ABI, gnu vs eabi. In this commit we make it gnu in both places to match the latest changes by @hoanga. * src/translate_c.zig
2021-02-25fix to compile against 12.0.0-rc2Michael Dusan
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
2020-12-24stage1: add tsan LLVM passes when appropriateAndrew Kelley
2020-12-16Update zig_llvm.cpp and other bitsJakub Konka
Include updates to corresponding zig sources llvm commit b2851aea80e5a8f0cfd6c3c5a56a6b00fb28c6b6
2020-12-08invoke LLD as a child process rather than a libraryAndrew Kelley
Closes #3825
2020-11-22Merge branch 'piepiepie' of https://github.com/LemonBoy/zig into pieAndrew Kelley
Conflicts: lib/std/dynamic_library.zig (fixed in this commit) src/all_types.hpp src/codegen.cpp src/link.cpp src/main.cpp Will manually apply the diffs to these deleted files to the new zig code in a followup commit.
2020-11-18Allow Zig to be built with clang 11 and -WerrorTimon Kruiper
This was brought to the horizon when using zig-bootstrap to cross compile Zig for windows-gnu.
2020-11-16Enable loop interleaving when unrolling is enabledFrank Denis
This mimics clang's default behavior.

2020-10-12Rename .macosx to .macosVignesh Rajagopalan
2020-10-07Merge remote-tracking branch 'origin/master' into llvm11Andrew Kelley
Conflicts: cmake/Findllvm.cmake The llvm11 branch changed 10's to 11's and master branch added the "using LLVM_CONFIG_EXE" help message, so the resolution was to merge these changes together. I also added a check to make sure LLVM is built with AVR enabled, which is no longer an experimental target.
2020-10-05stage1: Implement @reduce builtin for vector typesLemonBoy
The builtin folds a Vector(N,T) into a scalar T using a specified operator. Closes #2698

2020-07-24update LLVM C++ API wrappers from llvm 10 to 11Andrew Kelley
2020-04-03change the default ABI of riscv64-linux-muslAndrew Kelley
Before, this would cause a link failure when mixing Zig and C code for RISC-V targets. Now, the ABIs match and Zig and C code can be mixed successfully. I will file a follow-up issue for the ability to deal more explicitly with ABIs. closes #4863

2019-09-03fix stack traces on macos when passing absolute path to root source fileAndrew Kelley
The comment added by this commit is copied here: For macOS stack traces, we want to avoid having to parse the compilation unit debug info. As long as each debug info file has a path independent of the compilation unit directory (DW_AT_comp_dir), then we never have to look at the compilation unit debug info. If we provide an absolute path to LLVM here for the compilation unit debug info, LLVM will emit DWARF info that depends on DW_AT_comp_dir. To avoid this, we pass "." for the compilation unit directory. This forces each debug file to have a directory rather than be relative to DW_AT_comp_dir. According to DWARF 5, debug files will no longer reference DW_AT_comp_dir, for the purpose of being able to support the common practice of stripping all but the line number sections from an executable. closes #2700

2019-08-26remove no longer needed gcc8 workaround. add gcc9 workaroundAndrew Kelley
Occasionally LLVM headers generate warnings with newer gcc versions and since we use -Werror this has to be worked around.
