* 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
This takes the place of `zig builtin`. This is an improvement over the
command because now the generated source will correctly show LinkMode
and OutputMode, whereas before it was always stuck as Static and Obj,
respectively.
Deleted 16,000+ lines of c++ code, including:
* an implementation of blake hashing
* the cache hash system
* compiler.cpp
* all the linking code, and everything having to do with building
glibc, musl, and mingw-w64
* much of the stage1 compiler internals got slimmed down since it
now assumes it is always outputting an object file.
More stuff:
* stage1 is now built with a different strategy: we have a tiny
zig0.cpp which is a slimmed down version of what stage1 main.cpp used
to be. Its only purpose is to build stage2 zig code into an object
file, which is then linked by the host build system (cmake) into
stage1. zig0.cpp uses the same C API that stage2 now has access to,
so that stage2 zig code can call into stage1 c++ code.
- stage1.h is
- stage2.h is
- stage1.zig is the main entry point for the Zig/C++
hybrid compiler. It has the functions exported from Zig, called
in C++, and bindings for the functions exported from C++, called
from Zig.
* removed the memory profiling instrumentation from stage1.
Abandon ship!
* Re-added the sections to the README about how to build stage2 and
stage3.
* stage2 now knows as a comptime boolean whether it is being compiled
as part of stage1 or as stage2.
- TODO use this flag to call into stage1 for compiling zig code.
* introduce -fdll-export-fns and -fno-dll-export-fns and clarify
its relationship to link_mode (static/dynamic)
* implement depending on LLVM to detect native target cpu features when
LLVM extensions are enabled and zig lacks CPU feature detection for
that target architecture.
* C importing is broken, will need some stage2 support to function
again.
