Previously, --name would only be inferred if there was exactly 1 C
source file or exactly 1 object. Now it will be inferred if there is at
least one of either.
This allows to have multiple instances of `zig build` at the same
time. For example when you have a long running `zig build run` and
then want to run `zig build somethingelse`.
Closes#7356
I did this as a patch to the source rather than passing flags so that
it would intentionally be reverted when we update to the next release of
mingw-w64. At this time if any warnings are still emitted we should find
out why and make sure upstream is aware of the problem.
Let's a void any kind of compilation/LLVM errors for niche targets such
as AVR/MSP430 or ARM v6m. By not exporting any atomic builtin anymore
the user is free to provide their own implementation (that disable the
IRQs) or to provide the --single-threaded switch and forget about this.
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.
This commit adds:
ZIG_LOCAL_CACHE_DIR corresponding to --cache-dir
ZIG_GLOBAL_CACHE_DIR corresponding to --global-cache-dir
ZIG_LIB_DIR corresponding to --override-lib-dir
The main use case is for `zig cc` where we are bound by clang's CLI
options and need alternate channels to pass these configuration options.
Previously, when mixing Zig and C/C++ code for windows-gnu targets, zig
would get codeview format but the C/C++ code would not get any debug
info. Now, C/C++ code properly emits debug info in codeview format and
everything just works.
The code is a bit fragile so it was causing CI failures on x86_64-macos.
Also the patch up code is only needed for aarch64-macos, so we were
doing unnecessary work.
The readme now links to the wiki for instructions on building from
source. I plan to make many updates to the wiki soon as I start to
provide tarballs for working on the compiler.
restore cmake to be capable of figuring out the zig version
restore config.h and config.zig. config.h is used to detect whether we
should propagate cmake configuration information to build.zig; however
it can be overridden with -Dstatic-llvm.
fix not passing -DZIG_LINK_MODE with zig build.
when using the cmake build path, build.zig no longer tries to call
llvm-config. Instead it relies 100% on the LLVM_LIBRARIES cmake variable.
build.zig logic reworked and simplified.
