Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change
This instruction is not really working well in the LLVM SPIRV translator,
as it is not implemented.
This commit also intruces the constructStruct helper function to initialize
structs at runtime. This is ALSO buggy in the translator, and we must work
around OpCompositeConstruct not working when some of the constituents are
runtime-known only.
Some other improvements are made:
- improved variable() so that it is more useful and no longer requires the
address space. It always puts values in the Function address space,
and returns a pointer to the Generic address space
- adds a boolToInt utility function
- cbe: Implement linksection support, to support TLS when not linking libc
- cbe: Support under-aligned variables / struct fields
- cbe: Support packed structs (in the C definition of packed)
- windows: Fix regression with x86 _tls_array
- compiler_rt: Add 128-bit atomics to compiler_rt
- tests: Re-enable threadlocal tests on cbe+windows, and llvm+x86
- tests: Re-enable f80 tests that now pass
- ci: change windows ci to run the CBE behaviour tests with -lc, to match how the compiler is bootstrapped
- update zig1.wasm
- fixup 128-bit atomics test to only run on x86_64
- add truncation test for 128-bit types, including non power of two targets (there was a bug with broken non-power-of-two truncation in the cbe)
- add 128-bit binary not test (covers another bug fixed in the cbe)
This reverts commit 3370d58956ecc744a004dff47b0437473f0ef7da.
This commit was done with an LLVM build that did not have assertions
enabled. There are LLVM assertions being triggered due to this commit.
