We return compare flags rather than a register which than wrongly
cheats the regalloc into thinking we carry the instruction in the
register which we do not.
If the function call is not extern and we are compiling in debug,
pass function params always on stack. This will improve debugging
capabilities since the params will not be volatile and possibly
clobbered by the procedure code.
Finish implementation of `imul_complex`.
using the provided -L directories before checking if we need to integrate
with system library paths. This prevents false positive of invoking
system cc to find native paths when in fact all dependencies are
satisfied by -L (or --search-prefix to zig build).
* build.zig: remove detour through zig0. I'll add it back as an option
later. This means you can build stage1 with a freshly built zig
without detouring through zig0 again.
* remove unused file windows_script.bat
* drone.yml: remove unnecessary steps
* ninja doesn't need a jobs parameter
* build the release version of zig with zig build instead of cmake.
* build stage2 with -Dstatic-llvm -Duse-zig-libcxx
* Test everything on the Linux CI even if we can't run it, because it's
our fastest machine.
* Test stage2 using a build of stage2 (instead of using `-fno-stage1`)
so that compiler-rt is also built with stage2.
* Additionally test running x86_64-macos on the macOS CI, both the LLVM
backend and x86_64 backend.
This reverts commit baead472d7641bdd96130354bafadc1fb1ed223b.
Let's go through the proposal process on this one. I want to push back
on this. My position is that, at the very least, a full trace of command
lines of sub-processes should be printed on failure, with the exception
of opt-in flags such as `--prominent-compile-errors`.
If a '(' is found where the continue expression was expected and it is
on the same line as the previous token issue an error about missing
colon before the continue expression.
- Correctly get discard symbol by first checking if it was discarded or not.
- Remove imports if extern symbols were resolved by an object file.
- Correctly relocate data symbols by ensuring the atom is from the correct file.
- Fix the `Names` section by using the resolved symbols, rather than the ones defined in Zig code.
We now correctly allocate and create atoms for symbols from other object files.
Imports are now also resolved and appended when required.
Besides those changes, we now duplicate all symbol names, so we can correctly
generate unique names for unnamed constants.
TODO: String interning
This implements the merging of all sections, to generate a valid wasm binary where all symbols
have been resolved and their respective sections have been merged into the final binary.
This upstreams the object file parsing from zwld, bringing us closer to being able
to link stage2 code with object files/C-code as well as replacing lld with the self-hosted
linker once feature complete.

This provides a mechanism for builds to fully report an error to the user and prevent zig from piling on extra noise.
Non-Arm CPUs use u16 as the parameter to __extendhfxf2 and the return value of
__truncxfhf2, so insert appropriate bitcasts in gen_soft_f80_widen_or_shorten.
Otherwise, LLVM might crash because the functions are called in a different way
than its compiler-rt definition.
This fixes stage1 build on SPARCv9, and possibly other non-x86, non-Arm CPUs.
For some errors if the found token is not on the same line as
the previous token, point to the end of the previous token.
This usually results in more helpful errors.
