So that they can be referenced by getAllErrorsAlloc(). Fixes missing
compile errors.

since it's accessed by Compilation. fixes an invalid check of
bin_file==null
|
|
This field is needed by Compilation regardless of whether a link file is
instantiated.
Fixes an invalid check for bin_file=null.

* move wasi_emulated_libs into Compilation
- It needs to be accessed from Compilation, which needs to potentially
build those artifacts.
* Compilation: improve error reporting for two cases
- the setMiscFailure mechanism is handy - let's use it!
* fix one instance of incorrectly checking for emit_bin via
`comp.bin_file != null`. There are more instances of this that need to
be fixed in a future commit.
* fix renameTmpIntoCache not handling the case where it needs to make
the "o" directory in the zig-cache directory.
- while I'm at it, simplify the logic for handling the fact that
Windows returns error.AccessDenied rather than
error.PathAlreadyExists for failure to rename a directory over
another one.
* fix missing cache hash additions
- there are still more to add in a future commit -
addNonIncrementalStuffToCacheManifest is called when bin_file is
always null, and then it incorrectly checks if bin_file is non-null
and only then adds a bunch of stuff to the cache hash. It needs to
instead add to the cache hash based on lf_open_opts.

This is necessary because on COFF, the entry symbol name is not known
until the linker has looked at the set of global symbol names to
determine which of the four possible main entry points is present.
|
|
Now that we always pass --image-base to LLD, including when Zig chooses
the default value, LLD is complaining about 32-bit architectures because
it requires being at least equal to the max page size, which is 64K.

* fix relationship between createEmpty/open (similar logic as
607111aa758002bc51914b7dc800b23927c931b8)
* still resolve the start symbol when linking libc because when zig is
the linker it still needs to know the entry symbol.
* make use_llvm=false when there is no zig compilation unit.

It's now arena-allocated so no need to free it with gpa
|
|
|
|
This is redundant with CacheMode.whole which caches everything,
including linking output. Linker code does not need to concern itself
with caching like this.

it's not supposed to mutate Compilation like this.

implement builtin.zig file population for all modules rather than
assuming there is only one global builtin.zig module.
move some fields from link.File to Compilation
move some fields from Module to Compilation
compute debug_format in global Compilation config resolution
wire up C compilation to the concept of owner modules
make whole cache mode call link.File.createEmpty() instead of
link.File.open()

These options are only supposed to be provided to the initialization
functions, resolved, and then computed values stored in the appropriate
place (base struct or the object-format-specific structs).
Many more to go...

Much of the logic from Compilation.create() is extracted into
Compilation.Config.resolve() which accepts many optional settings and
produces concrete settings. This separate step is needed by API users of
Compilation so that they can pass the resolved global settings to the
Module creation function, which itself needs to resolve per-Module
settings.
Since the target and other things are no longer global settings, I did
not want them stored in link.File (in the `options` field). That options
field was already a kludge; those options should be resolved into
concrete settings. This commit also starts to work on that, deleting
link.Options, moving the fields into Compilation and
ObjectFormat-specific structs instead. Some fields were ephemeral and
should not have been stored at all, such as symbol_size_hint.
The link.File object of Compilation is now a `?*link.File` and `null`
when -fno-emit-bin is passed. It is now arena-allocated along with
Compilation itself, avoiding some messy cleanup code that was there
before.
On the command line, it is now possible to configure the standard
library itself by using `--mod std` just like any other module. This
meant that the CLI needed to create the standard library module rather
than having Compilation create it.
There are a lot of changes in this commit and it's still not done. I
didn't realize how quickly this changeset was going to balloon out of
control, and there are still many lines that need to be changed before
it even compiles successfully.
* introduce std.Build.Cache.HashHelper.oneShot
* add error_tracing to std.Build.Module
* extract build.zig file generation into src/Builtin.zig
* each CSourceFile and RcSourceFile now has a Module owner, which
determines some of the C compiler flags.

instead of passing it to Compilation separately and storing it
separately in the linker options.

This reverts commit 7161ed79c4abcaccdd56fe0b4fbd3d93472d41b8, reversing
changes made to 3f2a65594e1d3c0a4f4943a4ea522e8405db81e0.
Unfortunately, this sat in the PR queue too long and the merge broke the
zig1.wasm bootstrap process.
