2023-10-22child_process + Build: rename exec to run + all related codeJan Philipp Hafer
Justification: exec, execv etc are unix concepts and portable version should be called differently. Do no touch non-Zig code. Adjust error names as well, if associated. Closes #5853.
2023-09-19LLVM 17 std lib updates and fixesAndrew Kelley
* some manual fixes to generated CPU features code. in the future it would be nice to make the script do those automatically. I suspect the sm_90a thing is a bug in LLVM. * add liteos to various target OS switches. I know nothing about this OS; someone will need to work specifically on support for this OS when the time comes to support it properly in zig. * while waiting for the compiler, I went ahead and made more conservative choices about when to use `inline` in std/Target.zig

2023-02-04langref, tools: rename --single-threaded to -fsingle-threadedee7
Commit 40f5e5dfc60e ("CLI: introduce -fsingle-threaded/ -fno-single-threaded", 2021-12-01) removed the `--single-threaded` option, but didn't update all mentions of it. $ zig version 0.11.0-dev.1568+c9b957c93 $ zig build-exe --help | grep single -fsingle-threaded Code assumes there is only one thread -fno-single-threaded Code may not assume there is only one thread $ zig build-exe --single-threaded foo.zig error: unrecognized parameter: '--single-threaded'

2022-07-01update CPU features to LLVM 14Andrew Kelley
Notable changes: `_i386`, `_i486`, and `_i686` are renamed to `i386`, `i486`, and `i686` respectively. `std.zig.fmtId` is enhanced to support formatting `i386` as `@"i386"`. Some CPU features which are actually CPU models have been properly flattened, such as `apple_a12`, `apple_a13`, `apple_a7`, `cortex_a78c`, `exynos_m4`, `neoverse_e1`, `neoverse_n1`, `neoverse_n2`, `neoverse_v1`. Some CPU features have been added and some have been removed, following LLVM's lead. CSky CPU features support is added.

This works around a stage1 compiler bug resulting in a segfault when trying to use the tool.
2021-08-12compiler-rt: do not depend on `usingnamespace`Andrew Kelley
The idea is to depend on this language feature as little as possible with the hopes that it can be adjusted to be less of an anti-pattern. This also helps self-hosted, which does not yet implement `usingnamespace`, get closer to being able to build compiler-rt.

2021-06-17Fix `lakemont` CpuModel (#9099)d18g
Lakemont has no x86, no MMX, no SSE and no way of handling any fp-math. In theory LLVM is able to implicitly use the soft-float emulation library calls to legalize any such operation but, given Zig's use of many non-standard features, sometimes we hit a weak spot in the X86 codegen backend. Consider this as a work-around for this LLVM problem, fixing the problem in LLVM is not so high in my todo list as the target is pretty niche and Intel axed it in '19. (Commit message by @LemonBoy)
2021-06-13tools: Unbreak many toolsLemonBoy
Many tools were broken after the recent hash-table refactorings, fix them and ensure they won't silently break again.
2021-06-03Breaking hash map changes for 0.8.0Martin Wickham
- hash/eql functions moved into a Context object - *Context functions pass an explicit context - *Adapted functions pass specialized keys and contexts - new getPtr() function returns a pointer to value - remove functions renamed to fetchRemove - new remove functions return bool - removeAssertDiscard deleted, use assert(remove(...)) instead - Keys and values are stored in separate arrays - Entry is now {*K, *V}, the new KV is {K, V} - BufSet/BufMap functions renamed to match other set/map types - fixed iterating-while-modifying bug in src/link/C.zig

2021-04-20target: drop `ppc32` and prefer `ppc`Michael Dusan
- original PR #7949 (incorrectly) patched a generated-file and changes have subsequently been lost/overwritten - fix #7947 in a different way: drop `ppc32` because `ppc` already exists

2021-02-28tools/update_cpu_features: fix usage()Michael Dusan
2021-02-27update ARM target CPU featuresAndrew Kelley
This completes the process. All target CPU features are now auto-generated by the tools/update_cpu_features.zig script, which contains all the overrides. Invoking this tool against LLVM 12rc2 now produces an empty git diff.
2021-02-27tools/update_cpu_features: add a "flatten" featureAndrew Kelley
and use it to clean up aarch64 target CPU features
2021-02-27tools/update_cpu_features: better patching APIAndrew Kelley
With this change, added & modified cpus & features participate in the same pruning system, and sorting takes into account the zig name, not the pre-modified llvm name. The modified target files in this commit are due to the improved sorting and pruning. The script now fully supports extra cpus & features.

2021-02-27tools/update_cpu_features: prune redundant featuresAndrew Kelley
When a CPU feature implies that another one must be present, avoid redundantly specifying the other one.
2021-02-26tools/update_cpu_features: handle ISAs with no featuresAndrew Kelley
These are represented by not having a file for them.
2021-02-26tools/update_cpu_features: branch quota where necessaryAndrew Kelley
also avoid unnecessary escaping of single quotes inside double quoted strings (depends on a master branch commit that will be merged into this branch in a future commit)
2021-02-26introduce tools/update_cpu_features.zigAndrew Kelley
This replaces the previous target cpu features tool, taking advantage of llvm-tblgen --dump-json instead of trying to use python to parse the .td files. This is an initial version that has the basics working, including a simple feature override system, as well as multi-threaded processing. Follow-up commits will do clean ups to make the diff of the newly generated source files against previous versions be as desired.
