|
* DUALNUM: Handle integer type in JIT compiler.Mike Pall2011-03-101-14/+21
|

|
* FFI: Fix x86 code generation for ffi.string().Mike Pall2011-03-101-1/+1
|
* Fix code generation for bit.bnot().Mike Pall2011-03-071-1/+1
|
* DUALNUM: Make overflow guards weak. Add IR_USE and IR_MULOV.Mike Pall2011-03-071-0/+3
|
* Fix code generation for Intel Atom in x64 mode.Mike Pall2011-03-031-1/+1
|
* FFI: Fix compiled ffi.string() semantics.Mike Pall2011-02-281-1/+1
|
* Add IR_XBAR, a barrier against XLOAD/XSTORE optimizations.Mike Pall2011-02-071-1/+1
|
* FFI: Record simple C function calls.Mike Pall2011-02-051-25/+92
| | | | | | Only handles cdecl and fixarg C functions. Doesn't handle pass-by-value aggregates. Doesn't handle 64 bit args/returns on 32 bit CPUs.
* FFI: Rename IR_CNEWP to IR_CNEWI and use it to box 64 bit integers.Mike Pall2011-02-031-25/+42
| | | | | Generates smaller IR and DCE eliminates many intermediate boxes. Needs allocation sinking to eliminate the boxes kept alive by PHIs.
* Rename IR_POWI to IR_POW.Mike Pall2011-02-021-4/+4
|
* FFI: Record 64 bit integer divide and modulo.Mike Pall2011-02-021-5/+26
|
* Add SPLIT pass to split 64 bit IR instructions for 32 bit CPUs.Mike Pall2011-02-021-81/+363
| | | | | | | Add generic HIOP instruction for extra backend functionality. Add support for HIOP to x86 backend. Use POWI for 64 bit integer x^k, too. POWI is lowered to a call by SPLIT or the x64 backend.
* Combine i8/u8 XLOAD with BAND+comparison into test byte mrm, imm8.Mike Pall2011-01-191-0/+20
|
* Differentiate between IR_KPTR and IR_KKPTR.Mike Pall2011-01-191-3/+3
| | | | | | | IR_KPTR holds a const pointer to possibly non-const content. IR_KKPTR holds a const pointer to definitely const content. Note that only content known by the VM to be const qualifies. Content tagged as const by users (e.g. const char *) doesn't.
* FFI: Record 64 bit integer comparisons and pointer comparisons.Mike Pall2011-01-171-1/+1
|
* Bump copyright date to 2011.Mike Pall2011-01-091-1/+1
|
* Fix handling of floats in x86/x64 backend.Mike Pall2011-01-051-13/+17
|
* Add support for non-constant integer IR_MUL to backend.Mike Pall2011-01-031-27/+13
|

|

|
* Add support for uint64_t <-> FP conversions to x64 backend.Mike Pall2011-01-021-15/+34
|
* Add 8/16 to 32 bit sign/zero-extension variants to CONV.Mike Pall2010-12-311-1/+24
|

|

|
* Improve register allocation for loops with variable shifts.Mike Pall2010-12-231-1/+4
|
* Fix XSTORE for IRT_NUM constants.Mike Pall2010-12-201-1/+2
|
* FFI: Drop IR_CNEWI. Add IR_CNEWP only for pointers/refs.Mike Pall2010-12-171-58/+32
|
* FFI: Add IR_CNEW/IR_CNEWI to allocate/init cdata objects.Mike Pall2010-12-111-1/+90
|
* x86/x64 backend: keep invariants on the right rather than fusing loads.Mike Pall2010-12-091-3/+6
|
* Avoid fusing loads if there are multiple references.Mike Pall2010-12-081-8/+13
|
* Fix IRT_NUM support for XLOAD/XSTORE.Mike Pall2010-12-081-2/+3
|
