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.
As part of this:
* add std.process.cleanExit. closes#6395
- use it in several places
* adjust the alignment of text in `zig build --help` menu
* Cache: support the concept of "unhit" so that we properly keep track
of the cache when we find out using the secondary hash that the cache
"hit" was actually a miss. Use this to fix false negatives of caching
of stage1 build artifacts.
* fix not deleting the symlink hash for stage1 build artifacts causing
false positives.
* implement support for Package arguments in stage1 build artifacts
* update and add missing usage text
* add --override-lib-dir and --enable-cache CLI options
- `--enable-cache` takes the place of `--cache on`
* CLI supports -femit-bin=foo combined with --enable-cache to do an
"update file" operation. --enable-cache without that argument
will build the output into a cache directory and then print the path
to stdout (matching master branch behavior).
* errors surfacing from main() now print "error: Foo" instead of
"error: error.Foo".
* add CLI support for verbose debugging options
* implement building compiler_rt and libc static archive using stage1
C++ backend
* add function_sections and link_libcpp to root cache hash.
* cleanups to use the new Directory.join method.
* Package supports being initialized directly and cleaned up create()
method.
* fix classifyFileExt incorrectly saying .zir is .zig. Thanks
@Rocknest!
* unify updateSubCompilation implementations
HeapAllocator stores the pointer returned by HeapAlloc right after the
data block and, after the recent allocator refactoring, the space for
this pointer was not taken into account in the calculation of the final
block size.
Fixes#5830
* move stage2.cpp code into zig0.cpp for simplicity
* add -ftime-report and some more CLI options to stage2
* stage2 compites the llvm cpu features string
* classifyFileExt understands more file extensions
* correction to generateBuiltinZigSource using the wrong allocator
(thanks dbandstra!)
* stage2 is now able to build hello.zig into hello.o using stage1 as a
library however it fails linking due to missing compiler-rt
* remove dead code
* simplify zig0 builtin.zig source
* fix not resolving builtin.zig source path causing duplicate imports
* fix stage1.h not being valid C code
* fix stage2.h not being valid C code
