2011-04-17move helpers.h to helper.hLluís1-475/+0
This provides a consistent naming scheme across all targets. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-04-04target-arm: Use global env in iwmmxt_helper.c helpersPeter Maydell1-61/+61
Use the global 'env' variable in the helper functions in iwmmxt_helper.c. This means we don't need to pass env as an argument to them any more. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-04-03target-arm/helper.c: For float-int conversion helpers pass ints as intsPeter Maydell1-30/+30
Correct the argument and return types for the float<->int conversion helper functions so that integer arguments and return values are declared as uint32_t/uint64_t, not float32/float64. This allows us to remove the hand-rolled functions which were doing bitwise copies between the types via unions.

2011-02-20target-arm: Move Neon VZIP to helper functionsPeter Maydell1-0/+5
Move the implementation of the Neon VUZP unzip instruction from inline code to helper functions. (At 50+ TCG ops it was well over the recommended limit for coding inline.) The helper implementations also give the correct answers where the inline implementation did not.

2011-02-20target-arm: Move Neon VUZP to helper functionsPeter Maydell1-0/+6
Move the implementation of the Neon VUZP unzip instruction from inline code to helper functions. (At 50+ TCG ops it was well over the recommended limit for coding inline.) The helper implementations also fix the handling of the quadword version of the instruction.

2011-02-20target-arm: Implement VMULL.P8Peter Maydell1-0/+1

2011-02-10target-arm: Use standard FPSCR for Neon half-precision operationsPeter Maydell1-0/+2
The Neon half-precision conversion operations (VCVT.F16.F32 and VCVT.F32.F16) use ARM standard floating-point arithmetic, unlike the VFP versions (VCVTB and VCVTT). Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-02-09target-arm: Fix VQMOVUN Neon instruction.Juha Riihimäki1-0/+3
VQMOVUN does a signed-to-unsigned saturating conversion. This is different from both the signed-to-signed and unsigned-to-unsigned conversions already implemented, so we need a new set of helper functions (neon_unarrow_sat*).

2009-10-17target-arm: convert NEON VZIP/VUZP/VTRN helper functions to pure TCGFilip Navara1-6/+0
The neon_trn_u8, neon_trn_u16, neon_unzip_u8, neon_zip_u8 and neon_zip_u16 helpers used fixed registers to return values. This patch replaces that with TCG code, so T0/T1 is no longer directly used by the helper functions. Bugs in the gen_neon_unzip register load code were also fixed.
