* CompileStep: Avoid calling producesPdbFile() to determine whether the
option should be respected. If the user asks for it, put it on the
command line and let the Zig CLI deal with it appropriately.
* Make the namespace of `std.dwarf.Format.dwarf32` no longer have a
redundant "dwarf" in it.
* Add `zig cc` integration for `-gdwarf32` and `-gdwarf64`.
* Toss in a bonus bug fix for `-gdwarf-2`, `-gdwarf-3`, etc.
* Avoid using default init values for struct fields unnecessarily.
* Add missing cache hash addition for the new option.

Previously they were strong aliases, but as these types are used quite
intermittendly it resulted in a lot of toRef() calls. Removing them
improves readability a bit.

This makes -r treated the same as -c which is to output an object file.
Zig's ELF linker code already handles multiple object files into an
object file with the -r flag to LLD.

Also clean up parsing of linker args - reuse `ArgsIterator`.
In MachO, ensure we add every symbol marked with `-u` as undefined
before proceeding with symbol resolution. Additionally, ensure those
symbols are never garbage collected.
MachO entry_in_dylib test: pass `-u _my_main` when linking executable
so that it is not incorrectly garbage collected by the linker.

Partial revert of 1e963053d0ff67361b587b046a917375e963d5e9. Now that
lldb has a new method for accessing this data that does not require
manual updating, there is no longer any reason to share this data.

Implementation and tests ported from LLVM release 80.
Tests of __powihf2 created from __powisf2 tests with minor adjustments.
|
|
- Copy and adjust __divmodsi4 tests for __divmoddi4 and __divmodti4.
- Assuming d = a/b does not overflow (MIN/-1) or uses div by 0,
then tmp = (d * b) = (a/b * b) = a does not overflow.
=> Remove wraparound for remainder in applicable routines.
|
|
These are unused in LLVM, but in gcc used for example by rl78.
Move test files into common file, add tests for aforementioned routines
and missing ones for __lshrti3.

|
Follow up for #14541.

Commit 40f5e5dfc60e ("CLI: introduce -fsingle-threaded/
-fno-single-threaded", 2021-12-01) removed the `--single-threaded`
option, but didn't update all mentions of it.
$ zig version
0.11.0-dev.1568+c9b957c93
$ zig build-exe --help | grep single
-fsingle-threaded Code assumes there is only one thread
-fno-single-threaded Code may not assume there is only one thread
$ zig build-exe --single-threaded foo.zig
error: unrecognized parameter: '--single-threaded'

This commit adds support for "-x language" for a couple of hand-picked
supported languages. There is no reason the list of supported languages
to not grow (e.g. add "c-header"), but I'd like to keep it small at the
start.
Alternative 1
-------------
I first tried to add a new type "Language", and then add that to the
`CSourceFile`. But oh boy what a change it turns out to be. So I am
keeping myself tied to FileExt and see what you folks think.
Alternative 2
-------------
I tried adding `Language: ?[]const u8` to `CSourceFile`. However, the
language/ext, whatever we want to call it, still needs to be interpreted
in the main loop: one kind of handling for source files, other kind of
handling for everything else.
Test case
---------
*standalone.c*
#include <iostream>
int main() {
std::cout << "elho\n";
}
Compile and run:
$ ./zig run -x c++ -lc++ standalone.c
elho
$ ./zig c++ -x c++ standalone.c -o standalone && ./standalone
elho

Move the parsing of Root from the parse function to the Parser.parseRoot
method.
Add an empty line between each rule, for consistency with grammar.y.
Ensure that normal doc-comments are always on the top, for consistency.
Add extract-grammar.zig to the tools directory; it is used to extract
the PEG grammar from parse.zig, so that it can be compared with
grammar.y.

Allows dividing and formatting arbitrary-large unsigned integers.

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

After this, the machine code generated by zig matches identically to
gcc's after the differences in loading the have_lse flag.
|
|
* Rely on libSystem when targeting macOS.
* Make tools/gen_outline_atomics.zig more idiomatic.
* Remove the CPU detection / auxval checking from compiler_rt. This
functionality belongs in a different component. Zig's compiler_rt
must not rely on constructors. Instead it will export a symbol for
setting the value, and start code can detect and activate it.
* Remove the separate logic for inline assembly when the target does or
does not have lse support. `.inst` works in both cases.

enums so that we can branch to set `link_mode` properly when we iterate
over the clang arguments. also replaced `dynamic` flag in
clang_options_data.zig with proper definition similarly to `static`."
This reverts commit 6af0eeb58d1d220d407ce4c463eaeb25b35f2761.
This change needs more careful consideration. It regressed
zig-bootstrap due to cmake passing `-static -lkernel32` and zig failing
with error.UnableToStaticLink.
See https://github.com/ziglang/zig-bootstrap/issues/134

* Fix untagged struct names in debug info for llvm.
* Factor out common stage2 pretty printer data.
* Add lldb version of stage2 pretty printers.
