81c677d218 Add a bunch more set operations to the PowerPC backends, and the Pascal test 
for the same.

c4ad07fdfc Merge pull request #40 from davidgiven/dtrg-pas 
Make Pascal sets work on PowerPC (both ncg and mcg); make Pascal know about 8-bit bytes.

5ff983ad9b Increase the number of items in a char set from 128 to 256, to cover all 
possible bytes (7-bit bytes are so 70s).
 2017-01-15 22:30:25 +01:00
David Given
e7e29d34ff Add a test (currently failing) to check that Pascal char sets can store all 256 
possible values. Add the PowerPC ncg and mcg backend support to let the test
actually run, including modifying a bunch of PowrePC libem functions so that
they can be called from both ncg and mcg.

efab08178b Fix a bunch of issues with pushing and popping mismatched sizes, which the B 
compiler does a lot; dup 8 for pairs of words is now optimised.

5a38ce2a69 Pre-and-post-modification operators now work substantially better (i.e., 
working).

39215c131e Moved the inc/dec operator tests into their own source file; more exhaustive 
testing.

6b4f8d72b8 ine and ste are now declared to modify memory (preventing cached values being 
propagated across the modification).

7710c76d56 Introduce sequence points before store instructions to prevent loads from the 
same address being delayed until after the store (at which point they'll return
the wrong value).

0da248dced Use a better NOT; and after remembering that PowerPC bit numbers are all 
backwards in the documentation, rewrote IFEQ/IFLT/IFLE to actually work.
Probably. Thanks to the B test suite for spotting this.

aeb9d4952d Added an abmodules tool which detects B modules and generates an initialiser 
function for them (in C, unfortunately).

049aff9f33 Remove the negative-constant code from the compiler; I think it's going to
