Unlike IrInstruction[Foo]s, which all start with:
IrInstruction base;
AstNodes do not work like this, and instead use a pointer to their
specializations. The code assumed otherwise.
* `@clz`, `@ctz`, `@popCount`, `@bswap`, `@bitreverse` now
have a type parameter
* rename @bitreverse to @bitReverse
* rename @bswap to @byteSwap
Closes#2119Closes#2120
* fix crash when doing field access of slice types. closes#2486
* remove the deprecated Child property from slice types
* add -Dskip-non-native build option to build script
The code creates temporary ConstExprValue with global_refs set to
nullptr and that's carried over to the final value. Doing so prevents
the deduplication mechanism to work correctly, causing all sorts of
runtime crashes.
Fixes#1636Fixes#1608 (Even though it was already fixed by #1991)
This defines `@sizeOf` to be the runtime size of a type, which means
that it is zero for types such as comptime_int, type, and (enum
literal).
See #2209
const_ptr_pointee_unchecked did not take into account that if the
pointer is zero sized, then const_val->data.x_ptr.special would be
ConstPtrSpecialInvalid. This commit fixes this by also checking
that the child type of the pointer only have one possible value
and just returns that value.
Now that c58b802034 has removed
the "top of the comptime stack" requirement, the branch quota
can be modified somewhere other than the top of the comptime stack.
This means that the quota of a parent IrExecutable has to be
modifiable by an instruction in the child.
Closes#2261
there's a simple way to check for nan that does not need this header.
hryx on IRC reported that Linux Mint based on ubuntu 16.04, kernel
4.15.0, x86_64 did not have the isnan function.
Before only u0 was special cased in handling a dereference;
now all zero bit types are handled the same way. Dereferencing
a pointer to a zero bit type always gives a comptime-known
result.
This previously had been failing on master branch but went unnoticed
because until 846f72b57c the CI server was mistakenly not actually
running the single-threaded tests with --single-threaded.
This fixes the standard library tests with --single-threaded
--release-fast.
Not tested yet, but it builds.
This closes#761, and lays the groundwork for fixing the remaining
false positive "foo depends on itself" bugs, such as #624.
It also lays the groundwork for implementing ability to specify
alignment of fields (#1512).
