* fix a merge conflict discovered upon rebasing latest master
* rename Target.Cpu.Feature.Set.subSet to isSuperSetOf
* convert a comment into an assert
If there is a mismatch of CPU features provided
compared to the whitelist, then will fail the build and
print what the expected CPU model is and the feature
set for the model. Also prints what features need to be
removed.
- deprecates `std.Thread.spinLoopHint` and moves it to `std.atomic.spinLoopHint`
- added an Atomic(T) generic wrapper type which replaces atomic.Bool and atomic.Int
- in Atomic(T), selectively expose member functions depending on T and include bitwise atomic methods when T is an Integer
- added fence() and compilerFence() to std.atomic

- this one might be problematic; start.zig looks for `main` in the
root source file, not `_main`. Not sure why there is an underscore
there in master branch.

Mainly I wanted Jakub's new macOS code for respecting stack size, since
we now depend on it for debug builds able to pass one of the test cases
for recursive comptime function calls with `@setEvalBranchQuota`.
The conflicts were all trivial.
- 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
The avr1 target is a very minimal subset of the AVR ISA, quoting the GCC
manual:
> This ISA is implemented by the minimal AVR core and supported for
> assembler only.
Default to avr2 as GCC and Clang do.
The tools/update_cpu_features script is coming along, and generates
correct information for all these targets. The remaining targets are:
* arm
* aarch64
* amdgpu
* riscv
I will commit them once the issues with the updater tool are resolved.
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
* no isHaiku() function since there is not more than one os tag that
this applies to.
* clean up some control flow into a switch
* add some TODO comments to investigate panics that suspiciously look
like they should be compile errors (see #363)
The macOS version is now obtained by parsing `SystemVersion.plist`.
Test cases added for plist files that date back to '2005 Panther and up
to the recent '2020 Big Sur 11.1 release of macOS.
Thus we are now able to reliably identify 10.3...11.1 and higher.
- drop use of kern.osproductversion sysctl
- drop use of kern.osversion sysctl (fallback)
- drop kern.osversion tests
- add `lib.std.zig.system.detect()`
- add minimalistic parser for `SystemVersion.plist`
- add test cases for { 10.3, 10.3.9, 10.15.6, 11.0, 11.1 }
closes#7569
Rather than directly pasting the output from the
target-details-generator tool, we have to look at the diff line by line
and decide how to incorporate the changes.
The baseline abstraction is something that Zig provides.
The changes to x86 appear to be incorrect. After LLVM commit
3ad09fd03c51823aeb0bcbd7898aada33e9228d6 the CPU features are stored in
a different data layout in their tables, and so we need to update the
target details extraction tool to match.
