target-mips: fix EXTPDP and setting up pos field in the DSPControl reg

This change makes sure that modifications of pos field in the DSPControl
register do not trash other bits in the register. This bug can be triggered
with the additional test case in mips32-dsp/extpdp.c in this commit....

target-mips: fix incorrect behaviour for EXTP

The mask for EXTP instruction when size=31 has not been correctly
calculated.

The test (mips32-dsp/extp.c) has been extended to include the case that
triggers the issue.

Signed-off-by: Petar Jovanovic <>...

target-mips: fix incorrect behaviour for INSV

Corner case for INSV instruction when size=32 has not been correctly
implemented. The mask for size should be one bit wider, and preparing the
filter variable should be aware of this case too.

The test for INSV has been extended to include the case that triggers the...

target-mips: fix calculation of overflow for SHLL.PH and SHLL.QB

This change corrects and simplifies how discard is calculated for shift
left logical vector instructions. It is used to detect overflow and set bit
22 in the DSPControl register.

The existing tests (shll_ph.c, shll_qb.c) are extended with the corner cases...

target-mips: fix mipsdsp_mul_q15_q15 and tests for MAQ_SA_W_PHL/PHR

The operands for MAQ_SA_W.PHL/MAQ_SA_W.PHR must in specified format.
Otherwise, the results are unpredictable. Once the operands were corrected
in the tests (part of this change), a bug in mipsdsp_mul_q15_q15 became...

target-mips: fix rndrashift_short_acc and code for EXTR_ instructions

Fix for rndrashift_short_acc to set correct value to higher 64 bits.
This change also corrects conditions when bit 23 of the DSPControl register
is set.

The existing test files have been extended with several examples that...

target-mips: fix DSP overflow macro and affected routines

The previous implementation incorrectly used same macro to detect overflow
for addition and subtraction. This patch makes distinction between these
two, and creates separate macros. The affected routines are changed...

target-mips: fix incorrect test for MTHLIP

The pos field in the DSPControl register is not correctly initialized.
Per documentation, the result of MTHLIP is unpredictable if the value of the
pos field before the execution is greater than 32.

target-mips: Fix for helpers for EXTR_* instructions

The change removes some unnecessary and incorrect code for EXTR_S.H.
Further, it corrects the mask for shift value in the EXTR_ instructions. It also
extends the existing tests so they trigger the issues corrected with the change....

target-mips: Fix incorrect reads and writes to DSPControl register

Upper 4 bits of ccond (bits 31..28 ) of DSPControl register are not used in
the MIPS32 architecture. They are used in the MIPS64 architecture. For MIPS32
these bits must be written as zero, and return zero on read....
