We're going to remove the first parameter from this function in the
future. Stage2 already ignores the first parameter. So we put an `@as`
in here to make it work for both.
AstGen: Fixed bug where f80 types in source were triggering illegal
behavior.
Value: handle f80 in floating point arithmetic functions.
Value: implement floatRem and floatMod
This commit introduces dependencies on compiler-rt that are not
implemented. Those are a prerequisite to merging this branch.
When setting the break value in an if expression we must explicitly
check if a result location type coercion that needs to happen. This was
already done for switch expression, so let's just imitate that check
and fix for if expressions. To make this possible, we now also propagate
`rl_ty_inst` to sub scopes.
These options were removed in 5e63baae8 (CLI: remove --verbose-ast and
--verbose-tokenize, 2021-06-09) but some remainders were left in.

For PIE targets, we defer getting an address of value until the linker
has allocated all atoms and performed the relocations. In codegen,
we represent this via `MCValue.linker_sym_index` value.
- use usize to decide if register size is big enough to store
multiplication result or if division is necessary
- multiplication routine with check of integer bounds
- wrapping multipliation and division routine from Hacker's Delight
fieldVal handles pointer to pointer to array. This can happen for
example, if a pointer to an array is used as the condition expression of
a for loop.
resolveStructFully handles tuples (by doing nothing).
fixed Type comparison for tuples to handle comptime fields properly.
* resolve_inferred_alloc now gives a proper mutability attribute to the
corresponding alloc instruction. Previously, it would fail to mark
things const.
* slicing: fix the detection for when the end index equals the length
of the underlying object. Previously it was using `end - start` but
it should just use the end index directly. It also takes into account
when slicing a comptime-known slice.
* `Type.sentinel`: fix not handling all slice tags
Singular tests (such as in the bug ones) are moved to top level with exclusions for non-passing backends.
The big behavior tests such as array_llvm and slice are moved to the inner scope with the C backend disabled.
They all pass for the wasm backend now
We now calculate the total stack size required for the current frame.
The default alignment of the stack is 16 bytes, and will be overwritten when the alignment
of a given type is larger than that.
After we have generated all instructions for the body, we calculate the total stack size
by forward aligning the stack size while accounting for the max alignment.
We then insert a prologue into the body, where we substract this size from the stack pointer
and save it inside a bottom stackframe local. We use this local then, to calculate
the stack pointer locals of all variables we allocate into the stack.
In a future iteration we can improve this further by storing the offsets as a new `stack_offset` `WValue`.
This has the benefit of not having to spend runtime cost of storing those offsets, but instead we append
those offsets whenever we need the value that lives in the stack.
Implements the instruction `vector_init` for structs and arrays.
For arrays, it checks if the element must be passed by reference or not.
When not, it can simply use the `offset` field of a store instruction to copy the values
into the array. When it is byref, it will move the pointer by the element size, and then perform
a store operation. This ensures types like structs will be moved into the right position.
For structs we will always move the pointer, as we currently cannot verify if all fields are
not by ref.
This implements lowering elem_ptr for decl's and constants.
To generate the correct pointer, we perform a relocation by using the addend
that represents the offset. The offset is calculated by taking the element's size
and multiplying that by the index.
For constants this generates a single immediate instruction, and for decl's
this generates a single pointer address.
