- adds 1 simple behavior tests for each
which does integer and vector ops at
runtime and comptime
- adds bigint_*_sat() methods for each
- use CreateIntrinsic() which accepts a
variable number of arguments to pass
the scale parameter
* update langref
- added case to test/compile_errors.zig given floats
- explain upstream bug in llvm.smul.fix.sat and link to #9643 in langref and commented out test cases
* sat-arithmetic: skip mul tests if arch == .wasm32 because ci is erroring with 'LLVM ERROR: Unable to expand fixed point multiplication' when compiling for wasm32
* Added doc comments for `std.Target.ObjectFormat` enum
* `std.Target.oFileExt` is removed because it is incorrect for Plan-9
targets. Instead, use `std.Target.ObjectFormat.fileExt` and pass a
CPU architecture.
* Added `Compilation.Directory.joinZ` for when a null byte is desired.
* Improvements to `Compilation.create` logic for computing `use_llvm`
and reporting errors in contradictory flags. `-femit-llvm-ir` and
`-femit-llvm-bc` will now imply `-fLLVM`.
* Fix compilation when passing `.bc` files on the command line.
* Improvements to the stage2 LLVM backend:
- cleaned up error messages and error reporting. Properly bubble up
some errors rather than dumping to stderr; others turn into panics.
- properly call ZigLLVMCreateTargetMachine and
ZigLLVMTargetMachineEmitToFile and implement calculation of the
respective parameters (cpu features, code model, abi name, lto,
tsan, etc).
- LLVM module verification only runs in debug builds of the compiler
- use LLVMDumpModule rather than printToString because in the case
that we incorrectly pass a null pointer to LLVM it may crash during
dumping the module and having it partially printed is helpful in
this case.
- support -femit-asm, -fno-emit-bin, -femit-llvm-ir, -femit-llvm-bc
- Support LLVM backend when used with Mach-O and WASM linkers.
LLVM time profiler can collect time traces and present them in a
hierarchical view. Which breakdowns the time spent in each Pass or even
IR unit. The result is also exported into a format that can be easily
visualized by the Chrome browser.
Currently this features is controlled by the following environment
variables:
- `ZIG_LLVM_TIME_TRACE_FILE` toggles this feature and specifies the
output time trace file.
- `ZIG_LLVM_TIME_TRACE_GRANULARITY` controls the time granularity in
ms (default to 500).
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.

- 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.
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.

- 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
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.

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.
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.
