DSPAssembler: Rework errors and warnings, and related cleanup

Pokechu22 8d880cd86e DSPSpy: Add CMPAXH test 2022-05-27 18:22:38 -07:00
Pokechu22 8b52c7315b DSP: Fix assembling x8/x9/xA/xB conditions
The assembler upper-cases the mnemonic internally, so it never would match the lower-case x.

Pokechu22 c34a738b4c DSPSpy: Add missing jumps to end_of_test
Without this, execution continues beyond the end of the function, into the great unknown (probably eventually falling into either code left from a previous test, or the start of the DSP ROM). end_of_test is just an infinite loop to stop executing until the DSP is reset.

Pokechu22 464575702b DSPSpy: Replace less_test with cond_test
This new test covers all conditions, and also tests overflow, carry, logical zero, and the behavior of NEG

Pokechu22 f9e36bfa67 DSPLLE: Split SRS into SRS and SRSH
Hardware testing indicated that SRS uses a different list of registers than LRS (specifically, acS.h can be used with SRSH but not LRS, and SRS does not support AX registers, and there are 2 encodings that do nothing).

Pokechu22 51c26d82a5 DSPSpy: Require user to specify a test_main label
This makes the point where execution starts more obvious compared to a start_of_test label at the end of the include, and allows putting other functions at the start of the file.  This change also modifies the existing tests to build with this change.

Pokechu22 5f7c852d22 DSPSpy: Split main dsp_base logic from interrupt handlers
This is so that interrupt handlers can be manually specified in tests that need them.

Pokechu22 14119c86a4 DSPInterpreter: Fix IsLess
`IsLess` would incorrectly return true if both `SR_OVERFLOW` and `SR_SIGN` are set, as `(sr & SR_OVERFLOW) != (sr & SR_SIGN)` becomes `SR_OVERFLOW != SR_SIGN` which is true as the two masks are different.  This broke in e651592ef5.

This issue only affected the DSP LLE Interpreter, and not the DSP LLE JIT.

I've also included a simple test case for this.  `ax0.l` (on the top left) is set to 0 if the instruction following `IFL` does not execute and to 1 if it is executed.

Léo Lam 7c01127ac6 DSPSpy: Add a test for accelerator loop
This adds a test ucode that can be used to check the accelerator loop
behaviour with various start/end addresses.

It's actually more of a test template than a ready to use test.

Léo Lam e569d3bc4a DSPSpy/Base: Handle ACCOV exceptions
This allows dspspy to show that an ACCOV happened, and to resume
accelerator reads after an ACCOV (by refreshing the YN2 register).

Shawn Hoffman 4a0c8fc0c9 Hg:
enable newline normalization
get revision number via `hg svn info` for svnrev.h
ignore incremental/generated binary files (windows/VS at least)
leave a comment if some files need native eol set in svnprops

Soren Jorvang 664cea45c7 Meta:
Using Unix tools to operate on a tree containing filename with spaces in them
is really annoying, so rename the handful of instances where there were spaces.

Host.cpp has never been used.

Games tend to lookup the following directories that we don't yet have anything
to put in, so prepopulate them in Data/User/Wii:

title/00010001
title/00010002
title/00010003
title/00010004
title/00010005
title/00010006
title/00010007
meta
shared2/title
 
Set eol-style native on a number of text files which didn't already have it.
