For 2.2 Release. The following patchset implements MIPS SIMD Architecture module. MSA adds new instructions to MIPS Architecture that allow efficient parallel processing of vector operations.
For more information refer to: MIPS Architecture Reference Manual Volume IV-j: The MIPS32 SIMD Architecture Module The document (MD00867) is available at: http://www.imgtec.com/mips/architectures/simd.asp The MSA floating-point is compliant with the IEEE Standard for Floating-Point Arithmetic 754TM-2008. However this patchset is not set up with the IEEE-2008 option as QEMU softfloat for MIPS has not been updated yet. v3: * fixes for mixed declarations and code * remove duplicated code * change data format for immediate values v2: * fixes for Leon's and James' comments * rebased top of R6 patchset * Code refactored mainly for msa_helper.c Yongbok Kim (19): target-mips: add MSA defines and data structure target-mips: add MSA exceptions target-mips: remove duplicated mips/ieee mapping function target-mips: stop translation after ctc1 target-mips: add MSA opcode enum target-mips: add msa_reset(), global msa register target-mips: add msa_helper.c target-mips: add MSA branch instructions target-mips: add MSA I8 format instructions target-mips: add MSA I5 format instruction target-mips: add MSA BIT format instructions target-mips: add MSA 3R format instructions target-mips: add MSA ELM format instructions target-mips: add MSA 3RF format instructions target-mips: add MSA VEC/2R format instructions target-mips: add MSA 2RF format instructions target-mips: add MSA MI10 format instructions disas/mips.c: disassemble MSA instructions target-mips: add MSA support to mips32r5-generic disas/mips.c | 716 +++++++++- target-mips/Makefile.objs | 2 +- target-mips/cpu.h | 56 +- target-mips/gdbstub.c | 7 - target-mips/helper.c | 10 + target-mips/helper.h | 185 +++ target-mips/mips-defs.h | 1 + target-mips/msa_helper.c | 3437 ++++++++++++++++++++++++++++++++++++++++++ target-mips/op_helper.c | 89 +- target-mips/translate.c | 1647 +++++++++++++++++++-- target-mips/translate_init.c | 39 +- 11 files changed, 6052 insertions(+), 137 deletions(-) create mode 100644 target-mips/msa_helper.c -- 1.7.4
