Previously if a LinearFifo was empty and discard was called
an unsigned overflow would occur. However it is safe to perform
this overflow as a bitwise & operation with 0xFFFFFFFFFFFFFF is a noop
* std.log: still print error messages in ReleaseSmall builds.
- when start code gets an error code from main, it uses std.log.err
to report the error. this resulted in a test failure because
ReleaseSmall wasn't printing `error: TheErrorCode` when an error
was returned from main. But that seems like it should keep working.
So I changed the std.log defaults. I plan to follow this up with a
proposal to change the names of and reduce the quantity of the
log levels.
* warning emitted when using -femit-h when using stage1 backend; fatal
log message when using -femit-h with self-hosted backend (because the
feature is not yet available)
* fix double `test-cli` build steps in zig's build.zig
* update docgen to use new CLI
* translate-c uses `-x c` and generates a temporary basename with a
`.h` extension. Otherwise clang reports an error.
* --show-builtin implies -fno-emit-bin
* restore the compile error for using an extern "c" function without
putting -lc on the build line. we have to know about the libc
dependency up front.
* Fix ReleaseFast and ReleaseSmall getting swapped when passing the
value to the stage1 backend.
* correct the zig0 CLI usage text.
* update test harness code to the new CLI.
This is helpful on systems with multiple LLVM installations.
For example, OpenBSD ships with LLVM in the base system, but without
support for extra targets.
A full LLVM version can be installed using the ports system, but even
when it is, `cmake` is not going to pick it up unless `/usr/local` is
explicitly added to the `cmake` search paths.
Having the full `llvm-config` path printed on error is helpful to
understand that the detected LLVM version was not the expected one.
These CLI options are now forwarded to the stage1 backend.
We're not going to support the -mllvm CLI option any longer. As a
compromise, we unconditionally tell LLVM to output intel x86 syntax when
using -femit-asm.
Simplify stage1 logic; it no longer has the concept of an output
directory. --output-dir is no longer a valid CLI option. cmake uses
the `-femit-bin=[path]` option.
Note the changes to test/cli.zig. This breaks the CLI API that Godbolt
is using so we're going to want to open a PR to help them upgrade to the
new CLI for the upcoming Zig 0.7.0 release.
This cleans up how the CLI parses and handles -E, -S, and -c.
Compilation explicitly acknowledges when it is being used to do C
preprocessing.
-S is properly translated to -fno-emit-bin -femit-asm but Compilation
does not yet handle -femit-asm.
There is not yet a mechanism for skipping the linking step when there is
only a single object file, and so to make this work we have to do a file
copy in link.flush() to copy the file from zig-cache into the output
directory.
These APIs allow one to write code that is agnostic of whether it is
using an ArrayHashMap or a HashMap, which can be valuable. Specify
intent precisely: if you only need the count of the items, it makes
sense to have a function for that.
Normally when using LLD to link, Zig uses a file named "lld.id" in the
same directory as the output binary which contains the hash of the link
operation, allowing Zig to skip linking when the hash would be unchanged.
In the case that the output binary is being emitted into a directory which
is externally modified - essentially anything other than zig-cache - then
this flag would be set to disable this machinery to avoid false positives.
* Better defaults when using -fno-LLVM
* Fix compiler_rt and libc static libraries were getting a .zig
extension instead of .a extension.
* when using the stage1 backend, put the object file next to the
stage1.id file in the cache directory. this prevents an object file
from polluting the cwd when using zig from the CLI.
* prefix with the message level
* if the scope is not default, also prefix with the scope
This makes the stack trace test pass, with no changes to the
test case, because errors returned from main() now print
`error: Foo` just like they do in master branch.
* Don't try to generate C header files yet since it will only cause a
crash saying the feature is unimplemented.
* Rename the CLI options for release modes to use the `-O` prefix to
match C compiler precedent. Options are now `-ODebug`,
`-OReleaseFast`, `-OReleaseSafe`, `-OReleaseSmall`. The optimization
mode matches the enum tags of std.builtin.Mode. It is planned to, at
some point, rename std.builtin.Mode to std.builtin.OptimizationMode
and modify the tags to be lower case to match the style convention.
- Update build.zig code to support this new CLI.
* update std.zig.binNameAlloc to support an optional Version and update
the implementation to correctly deal with dynamic library version
suffixes.
