David Mak 52c731c312 core: Implement Not/UAdd/USub for booleans 
Not sure if this is deliberate or an oversight, but we implement it
anyway for consistency with other Python implementations.

David Mak 5ba8601b39 core: Remove ArrayValue variants of functions

ArrayLikeAccessor now.

David Mak 13f06f3e29 core: Refactor VarMap to IndexMap 
This is the only Map I can find that preserves insertion order while
also deduplicating elements by key.

David Mak 77de24ef74 core: Use BTreeMap for type variable mapping 
There have been multiple instances where I had the need to iterate over
type variables, only to discover that the traversal order is arbitrary.

This commit fixes that by adding SortedMapping, which utilizes BTreeMap
internally to guarantee a traversal order. All instances of VarMap are
now refactored to use this to ensure that type variables are iterated in
 the order of its variable ID, which should be monotonically incremented
 by the unifier.

David Mak c93ad152d7 core: Codegen for ellipsis expression as NotImplemented 
A lot of refactoring was performed, specifically with relaxing
expression codegen to return Option in case where ellipsis are used
within a subexpression.

David Mak a2fce49b26 core: Allocate exceptions at the beginning of function 
Only one instance of exception is necessary, as exceptions will always
be initialized before being thrown.

David Mak 60a503a791 core: Allocate more stack variables at the beginning of function 
All allocas for temporary objects are now placed in the beginning of the
function. Allocas for on-temporary objects are not modified because
these variables may appear in a loop and thus must be uniquely
allocated by different allocas.

David Mak 0c49b30a90 core: Restore debug info before function call is invoked 
Previously, the IR which sets up the call to the target function will
have its debug location pointing at the last argument of the function
call instead of the function call itself.

David Mak c7de22287e core: Fix restoration of stack address 
All allocas for temporary objects are now placed in the beginning of the
function. Allocas for on-temporary objects are not modified because
these variables may appear in a loop and thus must be uniquely
represented.

David Mak cb39f61e79 core: Fix passing structure arguments to extern functions 
All parameters with a structure type in extern functions are marked as
`byref` instead of `byval`, as most ABIs require the first several
arguments to be passed in registers before spilling into the stack.

`byval` breaks this contract by explicitly requiring all arguments to be
 passed in the stack, breaking interop with libraries written in other
 languages.

David Mak 176f250bdb core: Fix missing conversion to i1 for IfExp 2023-09-28 10:06:40 +08:00
David Mak acdb1de6fe meta: Improve documentation for various modified classes 2023-09-25 15:42:07 +08:00
David Mak 31dcd2dde9 core: Use i8 for boolean variable allocation 
In LLVM, i1 represents a 1-byte integer with a single valid bit; The
rest of the 7 upper bits are undefined. This causes problems when
using these variables in memory operations (e.g. memcpy/memmove as
needed by List slicing and assignment).

We fix this by treating all local boolean variables as i8 so that they
are well-defined for memory operations. Function ABIs will continue to
use i1, as memory operations cannot be directly performed on function
arguments or return types, instead they are always converted back into
local boolean variables (which are i8s anyways).

Fixes #315.

David Mak f1b0e05b3d core: Rename IR variables 
Because it is unclear which variables are expressions and
subexpressions, all variables which are previously anonymous are named
using (1) the control flow statement if available, (2) the possible name
of the variable as inferred from the variable name in Rust, and (3) the
"addr" prefix to indicate that the values are pointers. These three
strings are joint together using '.', forming "for.i.addr" for instance.

David Mak ff23968544 core: Add name parameter to gen_{var_alloc,store_target} 
This allows variables in the IR to be assigned a custom name as opposed
to names with a default prefix.
