* Fix incorrect result when the first digit after the decimal point is not 0-9 - eg 0x0.ap0
* Fix compiler panic when the number starts with `0X` with a capital `X` - eg 0X0p0
* Fix compiler panic when the number has a decimal point immediately after `0x` - eg 0x.0p0
Before this commit, glibc headers did the following mapping:
* (zig) mipsel-linux-gnu => (glibc) mipsel-linux-gnu
* (zig) mipsel-linux-gnu-soft => (glibc) (none)
* (zig) mips-linux-gnu => (glibc) mips-linux-gnu
* (zig) mips-linux-gnu-soft => (glibc) (none)
While the glibc ABI stubs used the (zig) gnueabi and gnueabihf ABIs,
and the stage2 available_libcs array listed:
* (zig) mipsel-linux-gnu
* (zig) mips-linux-gnu
The problem is the mismatch between the ABI component of the headers and
the stubs.
This commit makes the following clarifications:
* (zig) mips-linux-gnueabi means soft-float
* (zig) mipsel-linux-gnueabi means soft-float
* (zig) mips-linux-gnueabihf means hard-float
* (zig) mipsel-linux-gnueabihf means hard-float
Consequently, the glibc headers now do this mapping:
* (zig) mips-linux-gnueabihf => (glibc) mips-linux-gnu
* (zig) mipsel-linux-gnueabihf => (glibc) mipsel-linux-gnu
* (zig) mips-linux-gnueabi => (glibc) mips-linux-gnu-soft
* (zig) mipsel-linux-gnueabi => (glibc) mipsel-linux-gnu-soft
The glibc ABI stubs are unchanged, and the stage2 available_libcs
array's 2 entries are modified and it gains 2 more:
* (zig) mipsel-linux-gnueabi
* (zig) mipsel-linux-gnueabihf
* (zig) mips-linux-gnueabi
* (zig) mips-linux-gnueabihf
Now everything is consistent. Zig no longer recognizes a `mips-linux-gnu`
triple; one must use `mips-linux-gnueabi` (soft float) or
`mips-linux-gnueabihf` (hard float).
This commit introduces tools/update_glibc.zig to update the start files
for next time.
Some notable changes in recent glibc:
* abi-note.S has been changed to abi-note.c but we resist the change to
keep it easier to compile the start files.
* elf-init.c has been deleted upstream. Further testing should be done
to verify that binaries against glibc omitting elf-init.c still run
properly on oldel glibc linux systems.
Closes#4926
The previous commit (38b2d62092) regressed
the compile error test case for when doing saturating shift left of a
comptime-known negative RHS.
This commit additionally fixes the error for regular shifts in addition
to saturating shifts.
Saturating shift left (`<<|`) previously used the `ir_analyze_bin_op_math`
codepath rather than the `ir_analyze_bit_shift` codepath, leading to it
doing peer type resolution (incorrect) instead of using the LHS type as
the number of bits to do the saturating against.
This required implementing SIMD vector support for `@truncate`.
Additionall, this commit adds a compile error for saturating shift left
on a comptime_int.
stage2 does not pass these new behavior tests yet.

- Correctly load slice value on stack
- Implement WrapErrorUnionErr and payload
- Implement trunc, fix sliceLen and write undefined
- Implement slice as return type and argument
Note: This also fixes a memory leak for inferred error sets, and for usingnamespace
This reverts commit 725267f7c2, reversing
changes made to 2dae860de3.
This test is failing:
```zig
pub fn main() u8 {
var e = foo();
const i = e catch 69;
return i;
}
fn foo() anyerror!u8 {
return 5;
}
```
It's returning 69 instead of the expected value 5.
I'm working on a build.zig file where I'm leveraging InstallRawStep but I'd like to change the install dir. This allows the install dir to be changd and also enhances InstallRawStep to add more options in the future by putting them into a struct with default values. This also removes the need for an extra addInstallStepWithFormat function in build.zig.
from zig-specific options to generally recognized zig build options that
any project can take advantage of. See the updated usage text for more
details.
This mostly reverts commit 692c254336.
The test "for loop over pointers to struct, getting field from struct
pointer" is still failing on the CI so that one is not moved over.
This reverts commit 0a9b4d092f.
Hm, these are all passing for me locally. I'll have to do some
troubleshooting to figure out which one(s) are failing on the CI.
* stage1: change the `@typeName` of `@TypeOf(undefined)`,
`@TypeOf(null)`, and `@TypeOf(.foo)` to match stage2.
* move passing behavior tests to the passing-for-stage2 section.
Previously, when a coercion needed to be inserted into a break
instruction, the `br` AIR instruction would be rewritten so that the
block operand was a sub-block that did the coercion. The problem is that
the sub-block itself was never added to the parent block, resulting in
the `br` instruction operand being a bad reference.
Now, the `br` AIR instruction that needs to have coercion instructions
added is replaced with the sub-block itself with type `noreturn`, and
then the sub-block has the coercion instructions and a new `br`
instruction that breaks from the original block.
LLVM backend needed to be fixed to lower `noreturn` blocks without
emitting an unused LLVM basic block.
After extern enums were removed, stage1 was left in an incorrect state
of checking for `extern enum` for exported enums. This commit fixes it
to look for an explicit integer tag type instead, and adds test coverage
for the compile error case as well as the success case.
