* introduce --disable-pic option which can generally be allowed to be
the default. compiler_rt.a and builtin.a get this option when you
build a static executable.
* compiler_rt and builtin libraries are not built for build-lib
--static
* posix_spawn instead of fork/execv
* disable the error limit on LLD. Fixes the blank lines printed
init-lib creates a working static library with tests, and
init-exe creates a working hello world with a `run` target.
both now have test coverage with the new "cli tests" file.
closes#1035
* add almost all the input parameter state to the hash
- missing items are the detected MSVC installation on Windows
and detected libc installation on POSIX
- also missing are C files and .h files that libclang finds
* artifacts are created in global cache directory instead of
zig-cache.
- exception: builtin.zig is still in zig-cache
* zig run uses the new cache correctly
* zig run uses execv on posix systems
Issue: https://github.com/ziglang/zig/issues/1117
The macOS stage1 Zig compiler should look in Zig's real absolute path
for the Zig stdlib, but os_self_exe_path looks in its path as returned
by _NSGetExecutablePath, which may be a symlink. This means that a
symlinked Zig cannot find the Zig stdlib.
This patch fixes the issue by resolving the _NSGetExecutablePath result
to the real path using realpath() before copying the result to the
output path.
'zig run file.zig' builds a file and stores the artifacts in the global
cache. On successful compilation the binary is executed.
'zig run file.zig -- a b c' does the same, but passes the arguments a,
b and c as runtime arguments to the program. Everything after an '--' are
treated as runtime arguments.
On a posix system, a shebang can be used to run a zig file directly. An
example shebang would be '#!/usr/bin/zig run'. You may not be able pass
extra compile arguments currently as part of the shebang. Linux for example
treats all arguments after the first as a single argument which will result
in an 'invalid command'.
Currently there is no customisability for the cache path as a compile
argument. For a posix system you can use `TMPDIR=. zig run file.zig` to
override, in this case using the current directory for the run cache.
The input file is always recompiled, even if it has changed. This is
intended to be cached but further discussion/thought needs to go into
this.
Closes#466.
this removes the following configure options:
* ZIG_LIBC_LIB_DIR
* ZIG_LIBC_STATIC_LIB_DIR
* ZIG_LIBC_INCLUDE_DIR
* ZIG_DYNAMIC_LINKER
* ZIG_EACH_LIB_RPATH
* zig's reliance on CMAKE_INSTALL_PREFIX
these options are still available as command line options, however,
the default will attempt to execute the system's C compiler to
collect system defaults for these values.

Fixes: #517
I added a few things to allow zig to link with the CRT properly both statically and dynamically. In Visual Studio 2017, Microsoft changed how the c-runtime is factored again. With this change, they also added a COM interface to allow you to query the respective Visual Studio instance for two of them. This does that and also falls back on a registry query for 2015 support. If you're using a Visual Studio instance older than 2015, you'll have to use the existing options available with the zig compiler. Changes are listed below along with a general description of the changes.
all_types.cpp:
The separate variables for msvc/kern32 have been removed and all win32 libc directory paths have been combined into a ZigList since we're querying more than two directories and differentiating one from another doesn't matter to lld.
analyze.cpp:
The existing functions were extended to support querying libc libs & libc headers at runtime.
codegen.cpp/hpp:
Microsoft uses the new 'Universal C Runtime' name now. Doesn't matter from a functionality standpoint. I left the compiler switches as is to not introduce any breaking changes.
link.cpp:
We're linking 4 libs and generating another in order to support the UCRT.
Dynamic: msvcrt/d, vcruntime/d, ucrt/d, legacy_stdio_definitions.lib
Static: libcmt/d, libvcruntime/d libucrt/d, legacy_stdio_definitions.lib
main.cpp:
Update function call names.
os.cpp/hpp:
COM/Registry interface for querying Windows UCRT/SDK.
