This removes `report!`, `fatal!`, and `nonfatal!` from the verifier code and replaces them with methods on `VerifierErrors`. In order to maintain similar ease-of-use, `VerifierError` is expanded with several `From` implementations that convert a tuple to a verifier error.
This commit removes the dependency on `byteorder::ReadBytesExt`, which can't be
used from `no_std`, which is how we're building the `byteorder` crate.
The fix is to simply offset into the slice as needed rather than using a
`std::io::Cursor`.
Fixes#1225.
Due to SIMD's v128 operations, vectors that may have had an explicit type (e.g. f32x4) before a v128 operation will subsequently have CLIF's v128 stand-in type: i8x16. In order for follow-on operations (that may be more stricly typed, e.g. f32x4.add) to avoid CLIF errors, we must bitcast them back to the operation type. The raw_bitcast operation used to do this emits no machine code but does incur some small compile-time cost; it would be nice to avoid this in the future.
* Try and assign directly to return registers; backtrack to use struct-return param
Rather than trying to count number of return registers that would be used by a
given set of return values, optimistically assign the return values to
registers. If we later find that we can't fit them all in registers, then
backtrack and introduce the use of a struct-return pointer parameter.
* Rename `rets2` and wrap it in an option so we avoid the clone for non-multi-value
In some cases, compute_size() is used to choose between various different Encodings
before one has been assigned to an instruction. For x86, the REX.W bit is stored
in the Encoding. To share recipes between REX/non-REX, that bit must be inspected
by compute_size().
This commit fixes the build errors in the unwind info implementation for
the x86 ABI by changing `byteorder` to build `no_std`.
This copies two simple functions from the `WriteBytesExt` trait so that
we can easily write to a `Vec<u8>` with a particular endianness.
Fixes#1203.
* Implement SimpleJIT deallocation for non-windows targets.
* Remove custom Drop from feature(selinux-fix).
* Fix typo in unprotect error message.
* Drop SimpleJIT memory by default and add free_memory method instead.
* Move free_memory to a handle returned by Module::finish.
* Reduce memory handle content to necessary fields only.
* Use lower overhead method for leaking.
