The macOS version is now obtained by parsing `SystemVersion.plist`.
Test cases added for plist files that date back to '2005 Panther and up
to the recent '2020 Big Sur 11.1 release of macOS.
Thus we are now able to reliably identify 10.3...11.1 and higher.
- drop use of kern.osproductversion sysctl
- drop use of kern.osversion sysctl (fallback)
- drop kern.osversion tests
- add `lib.std.zig.system.detect()`
- add minimalistic parser for `SystemVersion.plist`
- add test cases for { 10.3, 10.3.9, 10.15.6, 11.0, 11.1 }

Rather than directly pasting the output from the
target-details-generator tool, we have to look at the diff line by line
and decide how to incorporate the changes.
The baseline abstraction is something that Zig provides.
The changes to x86 appear to be incorrect. After LLVM commit
3ad09fd03c51823aeb0bcbd7898aada33e9228d6 the CPU features are stored in
a different data layout in their tables, and so we need to update the
target details extraction tool to match.
* Smaller startup sequence for ppc64
* Terminate the frame-pointer chain when executing _start
* Make the stack traces work on ppc64
* Make the stack traces coloured on ppc64, some ioctls numbers are
different and the whole set of constants should be audited.
* std.Target.standardDynamicLinkerPath: macOS has a dynamic linker
* no need to override the default dynamic linker in the macos
CrossTarget initialization in the tests
* in getExternalExecutor, when validating the dynamic linker path, take
into account the standard dynamic linker path.
This is convenient for debugging purposes, as well as simplifying the
caching system since executable basenames will not conflict with their
corresponding object files.
* update to the new cache hash API
* std.Target defaultVersionRange moves to std.Target.Os.Tag
* std.Target.Os gains getVersionRange which returns a tagged union
* start the process of splitting Module into Compilation and "zig
module".
- The parts of Module having to do with only compiling zig code are
extracted into ZigModule.zig.
- Next step is to rename Module to Compilation.
- After that rename ZigModule back to Module.
* implement proper cache hash usage when compiling C objects, and
properly manage the file lock of the build artifacts.
* make versions optional to match recent changes to master branch.
* proper cache hash integration for compiling zig code
* proper cache hash integration for linking even when not compiling zig
code.
* ELF LLD linking integrates with the caching system. A comment from
the source code:
Here we want to determine whether we can save time by not invoking LLD when the
output is unchanged. None of the linker options or the object files that are being
linked are in the hash that namespaces the directory we are outputting to. Therefore,
we must hash those now, and the resulting digest will form the "id" of the linking
job we are about to perform.
After a successful link, we store the id in the metadata of a symlink named "id.txt" in
the artifact directory. So, now, we check if this symlink exists, and if it matches
our digest. If so, we can skip linking. Otherwise, we proceed with invoking LLD.
* implement disable_c_depfile option
* add tracy to a few more functions
* std.cache_hash exposes Hasher type
* std.cache_hash makes hasher_init a global const
* std.cache_hash supports cloning so that clones can share the same
open manifest dir handle as well as fork from shared hasher state
* start to populate the cache_hash for stage2 builds
* remove a footgun from std.cache_hash add function
* get rid of std.Target.ObjectFormat.unknown
* rework stage2 logic for resolving output artifact names by adding
object_format as an optional parameter to std.zig.binNameAlloc
* support -Denable-llvm in stage2 tests
* Module supports the use case when there are no .zig files
* introduce c_object_table and failed_c_objects to Module
* propagate many new kinds of data from CLI into Module and into
linker.Options
* introduce -fLLVM, -fLLD, -fClang and their -fno- counterparts.
closes#6251.
- add logic for choosing when to use LLD or zig's self-hosted linker
* stub code for implementing invoking Clang to build C objects
* add -femit-h, -femit-h=foo, and -fno-emit-h CLI options
Added std.coff.MachineType
Added image characteristic and section flag valued to std.coff
Added std.Target.Cpu.Arch.toCoffMachine
Fixed stage2 --watch flag on windows
* move SPU code from std to self hosted compiler
* change std lib comments to be descriptive rather than prescriptive
* avoid usingnamespace
* fix case style of error codes
* remove duplication of producer_string
* generalize handling of less than 64 bit arch pointers
* clean up SPU II related test harness code
