fixed an AssertionError also
* Remove deprecated functions
* Fix verifier printing to print instruction encodings consistently.
Use `FuncWriter::write_instruction` for all instructions so that
encodings are printed consistently.
* Make use-before-def errors mention the relevant value.
* When there are verifier errors, print a message at the end.
* Make verifier errors prettier.
Fix the length of the "^~~~~" to match the printed entity, and print the
error messsage on its own line.
* Clean up "test verifier" failure messages.
* Tidy the uses-value-from-itself error.
The use instruction is the same as the def instruction, so don't print
both. Also, the use instruction is already being printed at the
beginning, so don't print it again at the end.
* Move `return_at_end` out of Settings and into the wasm FuncEnvironment.
The `return_at_end` flag supports users that want to append a custom
epilogue to Cranelift-produced functions. It arranges for functions to
always return via a single return statement at the end, and users are
expected to remove this return to append their code.
This patch makes two changes:
- First, introduce a `fallthrough_return` instruction and use that
instead of adding a `return` at the end. That's simpler than having
users remove the `return` themselves.
- Second, move this setting out of the Settings and into the wasm
FuncEnvironment. This flag isn't something the code generator uses,
it's something that the wasm translator uses. The code generator
needs to preserve the property, however we can give the
`fallthrough_return` instruction properties to ensure this as needed,
such as marking it non-cloneable.
WebAssembly doesn't have non-dense jump tables, and higher-level users
are better served by the facilities in lib/frontend/src/switch.rs for
working with non-dense switches.
This eliminates the concept of "absent" jump table entries, which
were represented as "0" in the text format.
Also, jump table contents are now enclosed in `[` and `]`, so that
we can unambiguously display empty jump tables. Previously, empty jump
tables were displayed as if they had a single absent entry.
* Add 'jump_table_entry' and 'indirect_jump' instructions.
* Update CodeSink to keep track of code size. Pretty up clif-util's disassembly output.
* Only disassemble the machine portion of output. Pretty print the read-only data after it.
* Update switch frontend code to use new br_table instruction w/ default.
* Reorganize the global value kinds.
This:
- renames "deref" global values to "load" and gives it a offset that works
like the "load" instructions' does
- adds an explicit "iadd_imm" global value kind, which replaces the
builtin iadd in "vmctx" and "deref" global values.
- also renames "globalsym" to "symbol"
This makes several changes:
- It adds an index_type to heap declarations, allowing heaps to specify the
type for indexing. This also anticipates 64-bit heap support.
- It adds a memory_type to deref global values, allowing deref globals to
have types other than pointers. This is used to allow the bound variable
in dynamic heaps to have type i32, to match the index type in heaps
with i32 index type.
- And, it fixes heap legalization to do the bounds check in the heap's
index type.
* fix error not reported if at least one other error expected.
* Fixed unused extern crate error if wasm feature is not enabled.
* No longer reporting deref cycles multiple times.
* Fix filetest type_check.clif.
* Switched comparison order for perf.
* Fixed isa/riscv/verify-encoding.clif filetest.
* Fixed error reporting.
* Fixed compile time error when wasm feature is disabled.
* Fixed valid instructions not being printed in print_function_error.
* Fixed errors print_function_error not writing valid instructions after end.
* Made multiple checks non-fatal.
* verify_global_values is no longer fatal.
* Slightly better formatting of errors in pretty_verifier_error.
* Now diagnosing missing vmctx arguments (fixes#376).
* Added filetest for fix of #376.
* Respect formatting rules in verifier/mod.rs.
* Added parameters for each use of vmctx in test files.
* Added comments on additions on vmctx verifications.
* Update to rustfmt-preview.
* Run "cargo fmt --all" with rustfmt 0.4.1.
rustfmt 0.4.1 is the latest release of rustfmt-preview available on the
stable channel.
* Fix a long line that rustfmt 0.4.1 can't handle.
* Remove unneeded commas left behind by rustfmt.
* 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.
