Instead, just return ChildProcess directly. This structure does not
require a stable address, so we can put it on the stack just fine. If
someone wants it on the heap they should do.
const proc = try allocator.create(ChildProcess);
proc.* = ChildProcess.init(args, allocator);
18d6523888ef08bc66eb808075d13c5e00b8fcf4 regressed compiler-rt tests for
stage1 because it removed a workaround. I updated the comment to better
explain what exactly the workaround is so that it won't happen again.
This reverts commit 75c9936737a6ba991d4ef187ddc9d51bc0ad0998, reversing
changes made to 7f13f5cd5f5a518638b15d7225eae2d88ec1efb5.
I don't think `runZigBuild` belongs in std.testing. We already have
`test/standalone/*` for this.
Additionally test names should explain what they are testing rather than
referencing GitHub issue numbers.
This reverts commit 7f13f5cd5f5a518638b15d7225eae2d88ec1efb5.
I'd like to review this one before it goes in. This is an awfully
specific API that I don't think belongs in std.testing. Also I don't
want any code snippets in doc strings. We have doctests for that.
* remove need for manual string concatenation for building binaries in test blocks
* include small program snippet to show how to get binary path with subslicing
The reason for having `@tan` is that we already have `@sin` and `@cos`
because some targets have machine code instructions for them, but in the
case that the implementation needs to go into compiler-rt, sin, cos, and
tan all share a common dependency which includes a table of data. To
avoid duplicating this table of data, we promote tan to become a builtin
alongside sin and cos.
ZIR: The tag enum is at capacity so this commit moves
`field_call_bind_named` to be `extended`. I measured this as one of
the least used tags in the zig codebase.
Fix libc math suffix for `f32` being wrong in both stage1 and stage2.
stage1: add missing libc prefix for float functions.
* std.math.snan: fix compilation error. Also make it and nan inline.
* LLVM: use a proper enum type for float op instead of enum literal.
Also various cleanups.
* LLVM: use LLVMBuildVectorSplat for vector splat AIR instruction.
- also the bindings had parameter order wrong
* LLVM: additionally handle f16 lowering. For now all targets report OK
but I think we will need to add some exceptions to this list.
* unify the logic for exporting math functions from compiler-rt,
with the appropriate suffixes and prefixes.
- add all missing f128 and f80 exports. Functions with missing
implementations call other functions and have TODO comments.
- also add f16 functions
* move math functions from freestanding libc to compiler-rt (#7265)
* enable all the f128 and f80 code in the stage2 compiler and behavior
tests (#11161).
* update std lib to use builtins rather than `std.math`.
This function is codegen'd incorrectly in stage2, since it fails to
generate the correct soft-float operations. This will be fixed once
issue #11161 is implemented
With this change, it is now possible to safely call
`var di = std.debug.openSelfDebugInfo(gpa)`. Calling then
`di.deinit()` on the object will correctly free all allocated
resources.
Ensure we store the result of `mmap` with correct alignment.
Rather than allocating Decl objects with an Allocator, we instead allocate
them with a SegmentedList. This provides four advantages:
* Stable memory so that one thread can access a Decl object while another
thread allocates additional Decl objects from this list.
* It allows us to use u32 indexes to reference Decl objects rather than
pointers, saving memory in Type, Value, and dependency sets.
* Using integers to reference Decl objects rather than pointers makes
serialization trivial.
* It provides a unique integer to be used for anonymous symbol names,
avoiding multi-threaded contention on an atomic counter.
