Commit 5393e56500d499753dbc39704c0161b47d1e4d5c has a flaw pointed out
by @mlugg: the `ty` field of pointer values changes when comptime values
are pointer-casted. This commit introduces a new encoding which
additionally stores the "original pointer type" which is used to store
the alignment of the anonymous decl, and potentially other information
in the future such as section and pointer address space. However, this
new encoding is only used when the original pointer type differs from
the casted pointer type in a meaningful way.
I was able to make the LLVM backend and the C backend lower anonymous
decls with the appropriate alignment, however I will need some help
figuring out how to do this for the backends that lower anonymous decls
via src/codegen.zig and the wasm backend.
Instead of creating Module.Decl objects, directly create InternPool
pointer values using the anon_decl Addr encoding.
The LLVM backend needed code to notice the alignment of the pointer and
lower accordingly. The other backends likely need a similar change.
This completes the migration from spv.ptrType to self.ptrType.
Unfortunately this requires us to pass a list of types to
constructStruct, which also requires some extra allocations
here and there.
This removes the strategy where union with different active
fields would be generated, and instead simply pointer casts
the active field type where required. This also allows removing
spv.ptrType and using self.ptrType instead, and allows caching
all union types (because there is only the canonical one).
This struct is used to configure the load, such as to make
it volatile. Previously this was done using a single bool, but
this struct makes it shorter to write non-volatile loads (the
usual) and more clear whats going on when a volatile load is
required.
To support self-referential pointers, in the future we will
need to pass the Zig type to any pointer that is created. This
lays some ground work for that by replacing most uses of
spv.ptrType with a new ptrType function that also accepts the
Zig type. This function's contents will soon be replaced by
a version that also supports self-referential pointers.
Also fixed some bugs regarding the use of direct/indirect.
This reverts commit 78855bd21866b515018259a2194e036e4b3120df.
This commit did not replace uses of `Type.err_int` of which there are
currently 60 uses.
Re-opens #786
* support 0x prefixed hex code for CLI seed arguments
* don't change the build summary; the printed CLI on build runner
failure is sufficient
* use `std.crypto.random` instead of system time for entropy
This reverts commit d7b73af8f65bb891c8700ed47777144bb6f35fe1.
I did not look at this closely enough. This is incorrect; it should not
implicitly add rpaths for every library, and it should not disable the
nice default of each_lib_path when compiling for the native OS.
See #16062 where we are working on a follow-up improvement to this.
The INCLUDE variable being used during `.rc` preprocessing was an accidental regression in https://github.com/ziglang/zig/pull/17412.
Closes#17585.
resinator changes:
source_mapping: Protect against NUL bytes in #line filenames
lex: Avoid recalculating column on every tab stop within string literals
Proper error handling for failing to open cwd instead of `catch unreachable`
Use platform-specific delimiter for INCLUDE env var parsing
Before this commit, the logic would fail with a "LTO not available"
error if the user set `-fno-lto` which doesn't make sense. This commit
corrects the logic to understand when the user is explicitly requesting
to turn LTO off.
