2013-07-29target-mips: fix mipsdsp_mul_q31_q31Petar Jovanovic2-10/+58
Multiplication of two fractional word elements is not correct when sign extension/promotion is needed. This change fixes it by adding correct casts from unsigned to signed values. In addition, the tests (dpaq_sa_l_w.c and dpsq_sa_l_w.c) have been extended to trigger the current issue.

Multiplication of Q15 fractional halfword vectors was incorrect in the previous implementation of mipsdsp_rndq15_mul_q15_q15. It failed to take element signs into account. This change fixes it, and it adds a test case for it. The change also removes unnecessary cast in the function mipsdsp_mul_q15_q15_overflowflag21().

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. In addition to this, this change corrects incorrect calculation of the mask for EXTPDP.

2013-05-03target-mips: fix calculation of overflow for SHLL.PH and SHLL.QBPetar Jovanovic2-3/+53
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 that expose incorrectness in the previous implementation.

2013-04-15target-mips: fix mipsdsp_mul_q15_q15 and tests for MAQ_SA_W_PHL/PHRPetar Jovanovic2-18/+18
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 visible. This change corrects the tests for MAQ_SA_W.PHL/MAQ_SA_W.PHR and fixes sign-related issue in mipsdsp_mul_q15_q15. It also removes unnecessary comment.

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 trigger the issues. One bug/example in the test file for EXTR_RS_W has been found and reported by Klaus Peichl.

2013-03-04target-mips: fix DSP overflow macro and affected routinesPetar Jovanovic2-12/+46
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 accordingly. This change also includes additions to the existing tests for SUBQ_S_PH and SUBQ_S_W that would trigger the fixed issue, and it removes dead code from the test file. The last test case in subq_s_w.c is a bug found/reported/ isolated by Klaus Peichl from Dolby.

2013-01-01target-mips: Fix incorrect reads and writes to DSPControl registerPetar Jovanovic2-40/+24
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. The change fixes writes (WRDSP) and reads (RDDSP) to the register. It also fixes the tests that use these instructions, and makes them smaller and simpler. Signed-off-by: Petar Jovanovic <petarj@mips.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2012-11-10tests/tcg: new test for i386 FPREM and FPREM1Catalin Patulea2-0/+362
This is setting the stage for a cleanup of FPREM and FPREM1 helpers while being sure that they behave same as bare metal. The test constructs operands using combinations of corner cases for the floating-point bitfields and prints operands, result and FPU status word for FPREM and FPREM1. The outputs can then be compared between bare metal and QEMU. The 'run-test-i386-fprem' make target does just that.
