276ba8b97d Support systems which don't have a "python" command. (#386) 
Add support for finding an appropriate python command on systems which
don't have "python". Try "python3" and "python2.7".

Fixed #381.

8f3c49bc6c Update more references to "global variables". 
This continues the transition to "global values", which aren't
implicitly dereferenced.

7bed3426a7 Adds decoration to the verifier errors. (#375) 
* Adds decoration to the verifier errors.

example:

function %bad(i32) fast {
ebb0(v0: i32):
    brnz.i32 v0, ebb1
    return
    ^~~~~~

verifier inst1: Internal return not allowed with return_at_end=1

ebb1:
    trapz.i32 v0, user6
    return
}

Fixes #68

c5aad1eb5f Add support for macho relocations. (#378) 
This requires splitting X86PCRel4 into two separate relocations, to
distinguish the case where the instruction is a call, as Mach-O uses a
different relocation in that case.

This also makes it explicit that only x86-64 relocations are supported
currently.

d209137149 Rename TargetIsa's emit_function to emit_function_to_memory. 
This reflects the fact that it takes a concrete `MemoryCodeSink` rather than
a `CodeSink` trait object.

47a96641f9 Rename the memflags operand name from Flags to MemFlags. 
This reduces confusion with other kinds of flags.

1b55a2d005 Rename more Error and Result types. 2018-06-12 05:02:25 -07:00
Dan Gohman
6971ae1c26 Export CodegenError and CodegenResult at the top level. 
Make cretonne-codegen's `result` module private, and instead just export
`CodegenError` and `CodegenResult` at the top level of the
cretonne-codegen crate. This makes them more consistent with Result and
Error types in other cretonne crates.

02e34d1bf7 Make CtonError parameterized on the result type. 
This makes it more consistent with other custom `Result` types.

13f22065a2 Rename verifier's Result and Error. 
This provides consistency with similar types in other parts of
Cretonne, and avoids shadowing `Result` from the standard prelude.

0daa560368 Accept redundant alias definitions. 
In the text format, allow aliases to be defined multiple times, as long
as they're always aliasing the same value.

write.rs is already emitting redundant aliases, because it emits them at
their uses, so this change allows the parser to be able to parse such
code.

00d7d3a774 Implement IntoIterator for PrimaryMap. 
This makes iterating through a `PrimaryMap` more consistent with
iterating through a `Vec`.

970045c309 Set clobbers_flags to False for urm_noflags_abcd. 
`urm_noflags` is a variant of `urm` which doesn't clobber the flags, and
`urm_noflags_abcd` is a further variant for ABCD registers, so it also
doesn't clobber the flags.

4e67e08efd Use the target-lexicon crate. 
This switches from a custom list of architectures to use the
target-lexicon crate.

 - "set is_64bit=1; isa x86" is replaced with "target x86_64", and
   similar for other architectures, and the `is_64bit` flag is removed
   entirely.

 - The `is_compressed` flag is removed too; it's no longer being used to
   control REX prefixes on x86-64, ARM and Thumb are separate
   architectures in target-lexicon, and we can figure out how to
   select RISC-V compressed encodings when we're ready.
