[PATCH 00/19] Multiple ppc instructions fixes |
Date: |
Thu, 1 Sep 2022 10:17:37 -0300 |
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.
Patches 8 through 19 add 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.
Víctor Colombo (19):
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 VSX_CVT_INT_TO_FP_VECTOR
target/ppc: Clear fpstatus flags on VSX_CVT_INT_TO_FP
target/ppc: Clear fpstatus flags on VSX_CVT_FP_TO_FP
target/ppc: Clear fpstatus flags on VSX_CVT_FP_TO_INT_VECTOR
target/ppc: Clear fpstatus flags on VSX_CVT_FP_TO_INT2
target/ppc: Clear fpstatus flags on VSX_CVT_FP_TO_INT
target/ppc: Clear fpstatus flags on VSX_CVT_FP_TO_FP_HP
target/ppc: Clear fpstatus flags on VSX_CVT_FP_TO_FP_VECTOR
target/ppc: Clear fpstatus flags for xscvqpdp
target/ppc: Clear fpstatus flags for xscvdpsp[n]
target/ppc: Clear fpstatus flags on VSX_CMP
target/ppc: Clear fpstatus flags on VSX_ROUND
