This patch set fixes multiple instructions for PPC targets that were producing incorrect results, or setting the wrong bits in FPSCR. Patch 1 is just a style fix, trivial. Patch 8 adds helper_reset_fpstatus() calls to instructions that have an issue where the exception flags are being kept from the previous instruction, causing incorrect bits to be set, specially the non-sticky FI bit. Other patches fixes other specific situations. v1->v2: - Squash patches 8 through 19 and write a better commit message to it. - Dropped Daniel's R-b in the squashed patches, as the squash merged both reviewed and non-reviewed patches. Now require a new, single R-b. Víctor Colombo (8): target/ppc: Remove extra space from s128 field in ppc_vsr_t target/ppc: Remove unused xer_* macros target/ppc: Zero second doubleword in DFP instructions target/ppc: Set result to QNaN for DENBCD when VXCVI occurs target/ppc: Zero second doubleword for VSX madd instructions target/ppc: Set OV32 when OV is set target/ppc: Zero second doubleword of VSR registers for FPR insns target/ppc: Clear fpstatus flags on helpers missing it target/ppc/cpu.h | 6 +----- target/ppc/dfp_helper.c | 31 ++++++++++++++++++++++++++++--- target/ppc/fpu_helper.c | 39 +++++++++++++++++++++++++++------------ target/ppc/int_helper.c | 4 ++-- target/ppc/translate.c | 8 ++++++++ 5 files changed, 66 insertions(+), 22 deletions(-)
