* add a --system-linker-hack command line parameter to work around
poor LLD macho code. See #1535
* build.zig correctly handles static as well as dynamic dependencies
when building the self hosted compiler.
- no more unnecessary libxml2 dependency
- a static build on macos produces a completely static self-hosted
compiler for macos (except for libSystem as intended).
* add __multi3 compiler rt function. See #1290
* compiler rt includes ARM functions for thumb and aarch64 and
other sub-arches left out. See #1526
* support C ABI for returning structs on ARM. see #1481
* 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
Pass --no-entry instead of --relocatable to lld. Both stop a reference
to the _start() entry point from being emitted but --relocatable also
prevents public symbols from being exported when creating an executable.
This will make it easier to do things like `zig help | grep something`.
Invalid arguments will now display a short notice for `zig help`
instead of showing the full usage information. This will make it easier
to see the actual error.
On Arch Linux the current default compiler is gcc 8.2.1 and this change
is needed to ignore the following errors:
