* Start adding the load_complex and store_complex instructions.
N.b.:
The text format is not correct yet. Requires changes to the lexer and parser.
I'm not sure why I needed to change the RuntimeError to Exception yet. Will fix.
* Get first few encodings of load_complex working. Still needs var args type checking.
* Clean up ModRM helper functions in binemit.
* Implement 32-bit displace for load_complex
* Use encoding helpers instead of doing them all by hand
* Initial implementation of store_complex
* Parse value list for load/store_complex with + as delimiter. Looks nice.
* Add sign/zero-extension and size variants for load_complex.
* Add size variants of store_complex.
* Add asm helper lines to load/store complex bin tests.
* Example of length-checking the instruction ValueList for an encoding. Extremely questionable implementation.
* Fix Python linting issues
* First draft of postopt pass to fold adds and loads into load_complex. Just simple loads for now.
* Optimization pass now works with all types of loads.
* Add store+add -> store_complex to postopt pass
* Put complex address optimization behind ISA flag.
* Add load/store complex for f32 and f64
* Fixes changes to lexer that broke NaN parsing.
Abstracts away the repeated checks for whether or not the characters
following a + or - are going to be parsed as a number or not.
* Fix formatting issues
* Fix register restrictions for complex addresses.
* Encoding tests for x86-32.
* Add documentation for newly added instructions, recipes, and cdsl changes.
* Fix python formatting again
* Apply value-list length predicates to all LoadComplex and StoreComplex instructions.
* Add predicate types to new encoding helpers for mypy.
* Import FieldPredicate to satisfy mypy.
* Add and fix some "asm" strings in the encoding tests.
* Line-up 'bin' comments in x86/binary64 test
* Test parsing of offset-less store_complex instruction.
* 'sNaN' not 'sNan'
* Bounds check the lookup for polymorphic typevar operand.
* Fix encodings for istore16_complex.
* initial set of work for windows fastcall (x64) call convention
- call conventions: rename `fastcall` to `windows_fastcall`
- add initial set of filetests
- ensure arguments are written after the shadow space/store (offset-wise)
The shadow space available before the arguments (range 0..32)
is not used as spill space yet.
* address review feedback
Add a calling-convention setting to the `Flags` used as part of the
`TargetIsa`. This allows Cretonne code that generates calls to use the
correct convention, such as when emitting libcalls during legalization
or when the wasm frontend is decoding functions. This setting can be
overridden per-function.
This also adds "fast", "cold", and "fastcall" conventions, with "fast"
as the new default. Note that "fast" and "cold" are not intended to be
ABI-compatible across Cretonne versions.
This will also ensure Windows users will get an `unimplemented!` rather
than silent calling-convention mismatches, which reflects the fact that
Windows calling conventions are not yet implemented.
This also renames SpiderWASM, which isn't camel-case, to Baldrdash,
which is, and which is also a more relevant name.
