1 VIXL Change Log 2 =============== 3 4 * 1.4 5 + Added support for `frintm`. 6 + Fixed simulation of `frintn` and `frinta` for corner cases. 7 + Added more tests for floating point instruction simulation. 8 + Modified `CalleeSave()` and `CalleeRestore()` to push general purpose 9 registers before floating point registers on the stack. 10 + Fixed Printf for mixed argument types, and use on real hardware. 11 + Improved compatibility with some 32-bit compilers. 12 13 * 1.3 14 + Address inaccuracies in the simulated floating point instructions. 15 + Implement Default-NaN floating point mode. 16 + Introduce `UseScratchRegisterScope` for controlling the use of temporary 17 registers. 18 + Enable building VIXL on 32-bit hosts. 19 + Other small bug fixes and improvements. 20 21 * 1.2 22 + Added support for `fmadd`, `fnmadd`, `fnmsub`, `fminnm`, `fmaxnm`, 23 `frinta`, `fcvtau` and `fcvtas`. 24 + Added support for assembling and disassembling `isb`, `dsb` and `dmb`. 25 + Added support for automatic inversion of compare instructions when using 26 negative immediates. 27 + Added support for using `movn` when generating immediates. 28 + Added explicit flag-setting 'S' instructions, and removed 29 `SetFlags` and `LeaveFlags` arguments. 30 + Added support for `Movk` in macro assembler. 31 + Added support for W register parameters to `Tbz` and `Tbnz`. 32 + Added support for using immediate operands with `Csel`. 33 + Added new debugger syntax for memory inspection. 34 + Fixed `smull`, `fmsub` and `sdiv` simulation. 35 + Fixed sign extension for W->X conversions using `sxtb`, `sxth` and `sxtw`. 36 + Prevented code generation for certain side-effect free operations, 37 such as `add r, r, #0`, in the macro assembler. 38 + Other small bug fixes. 39 40 * 1.1 41 + Improved robustness of instruction decoder and disassembler. 42 + Added support for double-to-float conversions using `fcvt`. 43 + Added support for more fixed-point to floating-point conversions (`ucvtf` 44 and `scvtf`). 45 + Added instruction statistics collection class `instrument-a64.cc`. 46 47 * 1.0 48 + Initial release. 49
