Remove unused function parameters from gen_pc_load and rename the function
Function gen_pc_load was introduced in commitd2856f1ad4c259e5766847c49acbb4e390731bd4.The only reason for parameter searched_pc wasa debug statement in target-i386/translate.c....
Fix conversions from pointer to tcg_target_long
tcg_gen_exit_tb takes a parameter of type tcg_target_long,so the type casts of pointer to long should be replaced bytype casts of pointer to tcg_target_long (suggested by Blue Swirl).
These changes are needed for build environments where...
target-sh4: fix negc
Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
target-sh4: use rotl/rotr when possible
target-sh4: implement negc using TCG
Using setcond it's now possible to generate a relatively short negcinstruction in TCG.
target-sh4: define FPSCR constants
Define FPSCR constants for all field and use them instead of hardcodedvalues.
target-sh4: implement flush-to-zero
When the FPSCR.DN bit is set, the SH4 FPU treat denormalized numbers aszero. Enable the corresponding softfloat option when this bit is set.
target-sh4: add fipr instruction
Add the fipr FVm,FVn instruction, which computes the inner products ofa 4-dimensional single precision floating-point vector.
target-sh4: add ftrv instruction
Add the ftrv XMTRX,FVn instruction, which computes the 4-row x 4-columnmatrix XMTRX by the 4-dimensional vector FVn.
target-sh4: optimize exceptions
As exception is not the normal path, don't bother saving PC, beforeraising one, instead rely on code retranslation to get the CPU state.
target-sh4: fix reset on r2d
target-sh4: simplify comparisons after a 'and' op
When a TCG variable is anded with a value and the compared with the samevalue, we can simply invert the comparison and compare it with 0. Thegenerated code is smaller.
target-sh4: log instructions start in TCG code

Illegal instructions in a slot delay should generate a slot illegalinstruction exception instead of an illegal instruction exception.
The current PC should be saved before generating such an exception,but should not be corrected if in a delay slot, given it's already...
