* `type_size_store` is no longer a thing. loading and storing a pointer
to a value may dereference up to `@sizeOf(T)` bytes, even for
integers such as `u24`.
* fix `types_have_same_zig_comptime_repr` to not think that the
same `ZigTypeId` means the `ConstExprValue` neccesarily has the
same representation.
* implement `buf_write_value_bytes` and `buf_read_value_bytes` for
`ContainerLayoutPacked`
closes#1120
with this change, when you assign undefined, zig emits a few
assembly instructions to tell valgrind that the memory is undefined
it's on by default for debug builds, and disabled otherwise. only
support for linux, darwin, solaris, mingw on x86_64 is currently
implemented.
--disable-valgrind turns it off even in debug mode.
--enable-valgrind turns it on even in release modes.
It's always disabled for compiler_rt.a and builtin.a.
Adds `@import("builtin").valgrind_support` which lets code know
at comptime whether valgrind client requests are enabled.
See #1989
* Add docs for the inline function attribute
* Remove outdated comment
Seems like a leftover from when implicit returns were around.
* Consistent terminology
* also fix extern variables with initialiaztion values to generate runtime code
* remove the workaround in example/shared_library/mathtest.zig
* introduce the ability for global variables to have Weak and LinkOnce
linkage
* fix `@export` to work for non-functions. this code needs to be
audited though.
* fix comptime ptrcast not keeping bigger alignment
* fix linker warnings when targeting darwin
closes#1903
Mostly picking the same paths as FreeBSD.
We need a little special handling for crt files, as netbsd uses its
own (and not GCC's) for those, with slightly different names.
Previously, if a dereference instruction was an lvalue, it would fail to
typecheck that the value being dereferenced was indeed a pointer.
Although a little clunky, this change obviates the need for redundant
type checks scattered about the analysis.
