David Mak 068f0d9faf core: Do not cast floor/ceil result to int 
NumPy explicitly states that the return type of the floor/ceil is float.

preceding continue/break statement already emitting a terminator.

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.
 2023-10-06 11:42:47 +08:00
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.
 2023-10-06 11:35:23 +08:00
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 1a54aaa1c0 core: Restore debug location when generating allocas 
Debug location is lost when moving the builder cursor.

David Mak 9b28f23d8c flake: Add clang alongside clang-unwrapped 2023-09-30 09:31:18 +08:00
David Mak 48c6498d1f core: Fix restoration of loop target in try statement 
old_loop_target is only assigned if ctx.loop_target is overwritten,
meaning that if ctx.loop_target is never overwritten, ctx.loop_target
will always be overwritten to None.

We fix this by only restoring from old_loop_target if we previously
assigned to old_loop_target.

David Mak 2a38d5160e meta: Respect opt flags when performing whole-module optimization 2023-09-28 19:58:54 +08:00
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 e0de82993f core: Preserve value of variable shadowed by for loop 
Previously, the final value of the target expression would be one after
the last element of the loop, which does not match Python's behavior.

This commit fixes this problem while also preserving the last assigned
value of the loop beyond the loop, matching Python's behavior.

David Mak 6de0884dc1 core: Use anonymous name for variables if unspecified 
The current default prefix is only derived from the instruction type,
which is not helpful during the comprehension of the IR. Changing to
anonymous names (e.g. %1) helps understand that the variable is only
needed as part of a larger (possibly named) expression.
