Make sure to increase the reference count for `intcast` when the
operand doesn't require any casting of the respective WebAssembly type.
Function arguments have a reserved slot, and therefore cannot be
re-used arbitrarily
This fix ensures that when we are shifting left or right,
both operands have the same WebAssembly type. e.g. it's not possible
to shift a 64 bit integer and 32 bit integer together and will fail
WebAssembly's validator. By first coercing the values to the same
type, we ensure we satisfy the validator.
This was a special type tag used for hacky stuff in Semantic Analysis.
Move the hacky stuff to use a dedicated `Air.Inst.Ref` instead.
This way, `var_args_param` is not involved in the type system or intern
pool.

Thanks @jacobly for hints how to fix this on IRC.
* Avoid redundant words ("found")
- All compile errors are found by the compiler
* Avoid unnecessary prepositions ("with")
- There is a grammatically correct alternate word order without the
preposition.
This reverts commit 5aa9628de3c6637f45b9d8cf8cbd19c422a74f6f.
This is a breaking language change and I do not agree with it. Please go
through the proposal process on this one.
`@trap` is a special function that we know never returns so it should
behave just like `@panic` and `@compileError` do currently and cause the
"unreachable code" + "control flow is diverted here" compile error.
Currently, `@trap(); @trap();` does not cause this error. Now it does.
* When there is buffered cleartext, return it without calling the
underlying read function. This prevents buffer overflow due to space
used up by cleartext.
* Avoid clearing the buffer when the buffered cleartext could not be
completely given to the result read buffer, and there is some
buffered ciphertext left.
* Instead of rounding up the amount of bytes to ask for to the nearest
TLS record size, round down, with a minimum of 1. This prevents the
code path from being taken which requires extra memory copies.
* Avoid calling `@memcpy` with overlapping arguments.

When producing zig2.c, don't waste time emitting C code for subcommands
that won't be used, such as objcopy.
This takes zig2.c down from 111M to 109M, and sidesteps some unfortunate
warnings that are currently emitted by GCC.
* build.zig: the result of b.option() can be assigned directly in many
cases thanks to the return type being an optional
* std.Build: make the build system aware of the
std.Build.Step.Compile.BuildId type when used as an option.
- remove extraneous newlines in error logs
* simplify caching logic
* simplify hexstring parsing tests and use a doc test
* simplify hashing logic. don't use an optional when the `none` tag
already provides this meaning.
* CLI: fix incorrect linker arg parsing
In one of the happy paths, execve() is used to switch to clang in which
case any cleanup logic that exists for this temporary file will not run
and this temp file will be leaked. Oh well. It's a minor punishment for
using `-x c` which nobody should be doing. Therefore, we make no effort
to clean up. Using `-` for stdin as a source file always leaks a temp
file.
Note that the standard `zig build-exe` CLI does not support stdin as an
input file. This is only for `zig cc` C compiler compatibility.
* no need to move `tmpFilePath` around
* no need for calculating max length of `FileExt` tag name
* provide a canonical file extension name for `FileExt` so that, e.g.
the file will be named `stdin.S` instead of
`stdin.assembly_with_cpp`.
* move temp file cleanup to a function to reduce defer bloat in a large
function.
* fix bug caused by mixing relative and absolute paths in the cleanup
logic.
* remove commented out test and dead code

Is a common pattern to test for compiler or linker features. This patch
adds support for reading from non-regular files.
This will make at least one more Go test to pass.
Allows the package manager to download gitlab tarballs from urls such as
https://gitlab.com/<namespace>/<project>/-/archive/<sha>/<project>-<sha>.tar.gz
Such http requests have headers Content-Type=application/octet-stream
and Content-Disposition='attachment; filename="<project>-<sha>.tar.gz"'.
The package manager doesn't yet support these headers. This patch
doesn't attempt to properly parse the content-disposition header.
Instead it checks that it starts with 'attachment;' and ends with
'.tar.gz"'.
