Improve testing MachO binaries by verbose printing of the symtab
which includes segment,section names for defined symbols, and
import (dylib) name for imports.
This approach is more inline with what LLVM/LLD does for testing
of their output, and seems to be more generic and easier to extend
than implementing a lot of repetitive and nontrivial comparison
logic when working directly on structures.
CheckMachOStep specialises CheckFileStep into directed (surgical)
MachO file fuzzy searches. This will be the building block for
comprehensive MachO linker tests.
Instead, just return ChildProcess directly. This structure does not
require a stable address, so we can put it on the stack just fine. If
someone wants it on the heap they should do.
const proc = try allocator.create(ChildProcess);
proc.* = ChildProcess.init(args, allocator);
In accordance with the requesting issue (#10750):
- `zig test` skips any tests that it cannot spawn, returning success
- `zig run` and `zig build` exit with failure, reporting the command the cannot be run
- `zig clang`, `zig ar`, etc. already punt directly to the appropriate clang/lld main(), even before this change
- Native `libc` Detection is not supported
Additionally, `exec()` and related Builder functions error at run-time, reporting the command that cannot be run
I'm working on a build.zig file where I'm leveraging InstallRawStep but I'd like to change the install dir. This allows the install dir to be changd and also enhances InstallRawStep to add more options in the future by putting them into a struct with default values. This also removes the need for an extra addInstallStepWithFormat function in build.zig.
A new print field is added to RunStep that will control whether it prints the cmd before running it. By default it will be set to builder.verbose which means it will print only if builder.verbose is true.
This fixes InstallRawStep to handle the cases when there are empty segments (segments with no sections). Before this change, if there was an empty segment with no sections, then the fixup of binaryOffsets is skipped. This fixes that by looping through each segment until a non-empty one is found and then fixing up the sections. This fixed an issue I was having with InstallRawStep for a bootloader I'm writing.
This modifies the error for an unexpected exit code from the ChildProcess of RunStep to be UnexpectedExitCode rather than UncleanExit. This allows the handler of the error to distinguish between an error reported by the ChildProcess, and an error executing the ChildProcess, which is an important dinstinction when it comes to know what information to report to the user. For example, if you have a ChildProcess that you know reports its own errors, an unexpected exit code would mean the error is already reported, but an unclean exit would mean that child process was not able to report any error.
This allows writing HEX files with `exe.installRaw`, where `exe` is a
`LibExeObjStep`. A HEX file will be written if the file extension is `.hex`
or `.ihex`, otherwise a binfile will be written. The output format can be
explicitly chosen with `exe.installRawWithFormat("filename", .hex);`
(or `.bin`)

* rework `build_options` to integrate with the FileSource abstraction
* support mapping as an arbitrarily named package
* support mapping to multiple different artifacts
* use hash of contents for options filename
We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.
