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
Fixes#10915
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.
spirv: introduce SpvModule.Fn to generate function code into
spirv: assembler error message setup
spirv: runtime spec info
spirv: inline assembly tokenizer

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: OpTypeFunction
spirv: OpTypeOpaque

spirv: some stuff
spirv: remove spirv address spaces for now
* 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 6af0eeb58d.
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
* make the setting in the linker backend be non-optional; by this time
all defaults are supposed to be resolved.
* integrate with `zig cc`
* change the CLI parsing to match C compiler parsing, allowing
`--compress-debug-sections` alone to choose a default encoding of
zlib.
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.
Previously, updating the `SYS` enum for each architecture required
manually looking at the syscall tables and inserting any new additions.
This commit adds a tool, `generate_linux_syscalls.zig`, that automates
this process using the syscall tables in the Linux source tree. On
architectures without a table, it runs `zig cc` as a pre-processor to
extract the system-call numbers from the Linux headers.
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)
This was a bit trickier than it should be due to symbol conflicts with
zig's compiler-rt implementation. We attempt to use weak linkage in
our compiler-rt, but this does not seem to be working in all cases. I
manually disabled export of the problematic compiler-rt math functions
in order to cross compile musl's libc.so for all targets as input to
`tools/gen_stubs.zig`.
Other than that, this update went fairly smoothly. Quite a few
additional symbols were added to the blacklist in `tools/gen_stubs.zig`
due to recent reorganization of zig's compiler-rt.
