link: move ownership of linker atom from frontend to the linkers
|
|
|
|
This API only depends on std.Target and is extremely useful in build
scripts when populating configure files.
|
|
- 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

llvm: implement Stdcall calling convention
|
|
|
|
- add c_abi tests for .Stdcall
- enable (x86|x86_64)-windows-gnu in the c_abi tests

Closes #14261
|

This is a simple starting version of the optimization described in #168
where the fields are just sorted by order of descending alignment.

@bitCast from integer NaN representation to float NaN resulted in
changed bits in float. This only happened with signaled NaN.
- added test for signaled NaN
- added tests for quiet NaN (for completeness)
closes #14198

- Add cpuid / getXCR0 functions for the cbe to use instead of asm blocks
- Don't cast between 128 bit types during truncation
- Fixup truncation to use functions for shifts / adds
- Fixup float casts for undefined values
- Add test for 128 bit integer truncation
|
|
- add zig_mul_i128
- render slice structs in static initializers without casts / c99 style init
- add negative numbers and u128 to 128-bit multiply test
|
|
- Fix zig_clz_u128 not respecting the bits argument. This was crashing the compile-rt addxf3 tests with the cbe
- Instead of redering a negation for negative 128 bit int literals, render the literal as twos complement. This allows
rendering int representations of floats correctly (specifically f80).
|
|
- Implement most atomic operations for msvc
- Disable "atomicrmw with floats" test for cbe
|
|
|
|
|
|
- Add .StaticInitializer to ValueRenderLocation to indicate that the emitted values
must be constant expressions (no function calls, struct casting).
- Add new path for special float types (nan, inf) that works in constant expressions
- Implement windows.teb() using a syscall for .stage2_c because x64 MSVC
doesn't support any kind of inline asm
|
|
- Map the __builtin_nan(f|l)? functions to nan(f|l)? on msvc
- MSVC throws C2099 when initializing a struct with cast syntax
in a global initializer. Added zig_as_init_ to handle this case,
and generate it only in static initializers for > 64 bit ints.
- Change float initialization to emit the integer representation
in global initializers to avoid C2099 caused by calling nan.
|
|
- Handle non-abiInt source types (like packed union) as sources in renderIntCast
|
|
- Add Function.renderIntcast to handle common casting cases
- Fixup casting inside aggregate initialization
- Remove redundant cast in aggregate initialization
- Fix renderValue .Packed branch for > 64 bit types
|
|
64 bit
- Uses zig_as/zig_lo as necessary when int casting to support !zig_has_int128
- Remove redundant cast if the type is the same
- Use zig_lo when truncating > 64 bits
|
|
MSVC can't explicitly cast a struct to a typedef of itself (ie. f128 to i128). Added a
set of macros to handle float casting, and to not produce a cast for this specific
case on MSVC. A better approach would probably be to know if the cast is redundant
and not do it.

support
|
|
- Forward declare int builtins, so the definitions aren't assumed incorrectly
- Add define to handle MSVC not support static const in function parameter array lengths
- Fixup several spots where int128 support was assumed.
- Support zig_align
- Support zig_export
- Stub out some missing non-builtin functions
- Added StringLiteral to automatically split string literals when they get to 16380 in size,
which is the maxmimum pre-concatenation string literal size on MSVC.

When using llvm opaque pointers, typed pointers and pointer bitcasts are
no longer needed. This also avoids needing packed struct layouts that
are nested inside pointers, letting us avoid computing struct layouts
in Sema that could cause unnecessary dependency loops.

llvm: handle vectors in packed structs
|
|
Closes #13201
|
|
|
|
Normally when we want a pointer to the end of a struct we just add 1 to
the struct pointer. However, when it is a zero-bit struct, the pointer
type being used during lowering is often a dummy pointer type that
actually points to a non-zero-bit type, so we actually want to add 0
instead, since a zero-bit struct begins and ends at the same address.
|
|
* Initialize `big_align` with 1 as 0 is not a valid alignment.
* Add an assert to `alignForwardGeneric` to catch this issue earlier.
* Refactor valid alignment checks to call a more descriptive function.
