VIXL Change Log

• 1.4

  • Added support for frintm.
  • Fixed simulation of frintn and frinta for corner cases.
  • Added more tests for floating point instruction simulation.
  • Modified CalleeSave() and CalleeRestore() to push general purpose registers before floating point registers on the stack.
  • Fixed Printf for mixed argument types, and use on real hardware.
  • Improved compatibility with some 32-bit compilers.

• 1.3

  • Address inaccuracies in the simulated floating point instructions.
  • Implement Default-NaN floating point mode.
  • Introduce UseScratchRegisterScope for controlling the use of temporary registers.
  • Enable building VIXL on 32-bit hosts.
  • Other small bug fixes and improvements.

• 1.2

  • Added support for fmadd, fnmadd, fnmsub, fminnm, fmaxnm, frinta, fcvtau and fcvtas.
  • Added support for assembling and disassembling isb, dsb and dmb.
  • Added support for automatic inversion of compare instructions when using negative immediates.
  • Added support for using movn when generating immediates.
  • Added explicit flag-setting ‘S’ instructions, and removed SetFlags and LeaveFlags arguments.
  • Added support for Movk in macro assembler.
  • Added support for W register parameters to Tbz and Tbnz.
  • Added support for using immediate operands with Csel.
  • Added new debugger syntax for memory inspection.
  • Fixed smull, fmsub and sdiv simulation.
  • Fixed sign extension for W->X conversions using sxtb, sxth and sxtw.
  • Prevented code generation for certain side-effect free operations, such as add r, r, #0, in the macro assembler.
  • Other small bug fixes.

• 1.1

  • Improved robustness of instruction decoder and disassembler.
  • Added support for double-to-float conversions using fcvt.
