This adds a general target for SPIR-V compilation. Previously there was not
any target machine defined for SPIR-V.
TODO is to reword the features for this target. We don't really need the full
list of capabilities in the features, we should only put a few features here
which we can actually use during code generation.
spirv: introduce SpvModule.Fn to generate function code into
spirv: assembler error message setup
spirv: runtime spec info
spirv: inline assembly tokenizer
spirv: inline assembly lhs result/opcode parsing
spirv: forgot to fmt
spirv: tokenize opcodes and assigned result-ids
spirv: operand parsing setup
spirv: assembler string literals
spirv: assembler integer literals
spirv: assembler value enums
spirv: assembler bit masks
spirv: update assembler to new asm air format
spirv: target 1.5 for now
Current vulkan sdk version (1.3.204) ships spirv tools targetting 1.5,
and so these do not work with binaries targetting 1.6 yet. In the
future, this version number should be decided by the target.
spirv: store operands in flat arraylist.
Instead of having dedicated Operand variants for variadic operands,
just flatten them and store them in the normal inst.operands list.
This is a little simpler, but is not easily decodable in the operand
data representation.
spirv: parse variadic assembly operands
spirv: improve assembler result-id tokenization
spirv: begin instruction processing
spirv: only remove decl if it was actually allocated
spirv: work around weird miscompilation
Seems like there are problems with switch in anonymous struct literals.
spirv: begin resolving some types in assembler
spirv: improve instruction processing
spirv: rename some types + process OpTypeInt
spirv: process OpTypeVector
spirv: process OpTypeMatrix and OpTypeSampler
spirv: add opcode class to spec, remove @exclude'd instructions
spirv: process more type instructions
spirv: OpTypeFunction
spirv: OpTypeOpaque
spirv: parse LiteralContextDependentNumber operands
spirv: emit assembly instruction into right section
spirv: parse OpPhi parameters
spirv: inline assembly inputs
spirv: also copy air types
spirv: inline assembly outputs
spirv: spir-v address spaces
spirv: basic vector constants/types and shuffle
spirv: assembler OpTypeImage
spirv: some stuff
spirv: remove spirv address spaces for now
* Export invalidFmtErr
To allow consistent use of "invalid format string" compile error
response for badly formatted format strings.
See https://github.com/ziglang/zig/pull/13489#issuecomment-1311759340.
* Replace format compile errors with invalidFmtErr
- Provides more consistent compile errors.
- Gives user info about the type of the badly formated value.
* Rename invalidFmtErr as invalidFmtError
For consistency. Zig seems to use “Error” more often than “Err”.
* std: add invalid format string checks to remaining custom formatters
* pass reference-trace to comp when building build file; fix checkobjectstep
PR #13101 recently renamed the "i386" architecture to "x86", and it
seems the specific CPU model got swept up in that. "x86" is an umbrella
term that describes a family of CPUs, and the "i386" is the oldest
supported model under that umbrella.
This function is redundant with CType.sizeInBits(), and until the
previous commit they disagreed about the correct long double type
for several targets. Although they're all synced up now, it's much
simpler just to have a single source of truth.
These updates were made by testing against the `sizeof/_Alignof` reported
by Clang for all supported arch-OS-ABI combinations and correcting any
discrepancies.
This is bound to have a few errors (the recent long double fix for i386
Android is one example), but Clang is certainly not a bad place to start,
especially for our most popular targets.
This makes the following changes for i386:
long long and unsigned long long have 4 byte alignment on non-Windows
f64 (double) has 4-byte alignment on non-Windows
long double is 80 bits and has 4 byte alignment on mingw
long double on android is 64 bits, not 80: https://www.uclibc.org/docs/psABI-i386.pdfFixes#12453Fixes#12987
* riscv64: adjust alignment and size of 128-bit integers.
* take ofmt=c into account for ABI alignment of 128-bit integers and
structs.
* Type: make packed struct support intInfo
* fix f80 alignment for i386-windows-msvc
Notable changes:
`_i386`, `_i486`, and `_i686` are renamed to `i386`, `i486`,
and `i686` respectively. `std.zig.fmtId` is enhanced to support
formatting `i386` as `@"i386"`.
Some CPU features which are actually CPU models have been
properly flattened, such as `apple_a12`, `apple_a13`, `apple_a7`,
`cortex_a78c`, `exynos_m4`, `neoverse_e1`, `neoverse_n1`,
`neoverse_n2`, `neoverse_v1`.
Some CPU features have been added and some have been removed, following
LLVM's lead.
CSky CPU features support is added.
Prior to this change we would assume the ABI for Apple targets to
be GNU which could result in subtle errors in LLVM emitting calls
to non-existent system libc provided functions such as `_sincosf`
which is a GNU extension and as such is not provided by macOS for example.
This would result in linker errors where the linker would not be
able to find the said symbol in `libSystem.tbd`.
With this change, we now correctly identify macOS (and other Apple
platforms) as having ABI `unknown` which translates to unspecified
in LLVM under-the-hood:
```
// main.ll
target triple = "aarch64-unknown-macos-unknown"
```
Note however that we never suffix the target OS with target version
such as `macos11` or `macos12` which means we fail to instruct LLVM
of potential optimisations provided by the OS such as the availability
of function `___sincosf_stret`. I suggest we investigate that in a
follow-up commit.
Rename all references of sparcv9 to sparc64, to make Zig align more with
other projects. Also, added new function to convert glibc arch name to Zig
arch name, since it refers to the architecture as sparcv9.
This is based on the suggestion by @kubkon in PR 11847.
(https://github.com/ziglang/zig/pull/11487#pullrequestreview-963761757)
These targets now have a similar disagreement with LLVM about the
alignment of 128-bit integers as x86_64:
* riscv64
* powerpc64
* powerpc64le
* mips64
* mips64el
* sparcv9
