David Given 09c79b7dba Fix cosmetic warning when compiling B. 2017-01-15 23:00:17 +01:00
David Given 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.
2017-01-15 22:56:06 +01:00
David Given b32be06881 Allow the full 8-bit byte range when reading program source. 2017-01-15 22:41:11 +01:00
David Given 5fd1634830 Rename the test to something more sensible. 2017-01-15 22:33:41 +01:00
David Given 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.
2017-01-15 22:28:14 +01:00
David Given 1ea46f6afe Actually tell the user which tests failed. 2017-01-15 22:26:09 +01:00

top-level statement.

Fixes: #30

Add execve() system call for Linux
2017-01-07 23:23:00 +01:00
David Given 893471a42e No longer truncate module names at 10 characters when constructing paths;
rename some library modules to their full names.
2017-01-07 23:00:52 +01:00
David Given d50a6f99de Run through clang-format. 2017-01-07 22:56:00 +01:00

David Given abbead482a Sections are now aligned (required by the EM spec). 2017-01-07 18:47:46 +01:00
David Given 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.
2017-01-07 18:47:00 +01:00
David Given 5a38ce2a69 Pre-and-post-modification operators now work substantially better (i.e.,
working).
2017-01-07 18:46:03 +01:00
David Given 39215c131e Moved the inc/dec operator tests into their own source file; more exhaustive
testing.
2017-01-07 18:38:43 +01:00
David Given 6b4f8d72b8 ine and ste are now declared to modify memory (preventing cached values being
propagated across the modification).
2017-01-07 13:25:09 +01:00
David Given 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).
2017-01-07 13:17:39 +01:00
David Given 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.
2017-01-07 01:03:15 +01:00
David Given 77fc62285d Extern variables can now be written to. 2017-01-06 23:24:05 +01:00
David Given 73922f1d16 Ensure that procedure labels are word-aligned. 2017-01-06 22:29:52 +01:00
Xin Wang 24d26b2826 Add execve() system call for Linux 2017-01-06 18:33:52 +08:00
David Given 72766a02de Fix typo in the descr file which was stopping -B from working. Add B
documentation to the ack man page.
2017-01-04 13:28:40 +00:00
David Given aeb9d4952d Added an abmodules tool which detects B modules and generates an initialiser
function for them (in C, unfortunately).
2017-01-03 18:54:13 +00:00
David Given e2751f76b5 Add a control flow test. 2017-01-01 23:51:48 +00:00

now work.
2017-01-01 23:28:41 +00:00

David Given 049aff9f33 Remove the negative-constant code from the compiler; I think it's going to
break a=-1 (with no spaces). Backed out changeset dead3363ac7d.
2017-01-01 17:44:55 +00:00
David Given be909fe045 Add tests for more operators. 2017-01-01 17:44:03 +00:00

David Given 1beedca590 Add support for B tests; add a test for the B operators (finding several
compiler bugs in the process).
2016-12-31 17:38:52 +00:00
David Given 803b81e3f4 Add support for the xor operator. 2016-12-31 17:36:12 +00:00
David Given c3e1ef1064 B patch table names shouldn't be in the B symbol namespace. 2016-12-31 00:14:28 +00:00
David Given fa02a855e8 Fix issue where !x was actually calculating !!x. 2016-12-31 00:14:04 +00:00
David Given 462529a7d2 Trying to install openbios-ppc causes Travis to error out now (not sure why). 2016-12-29 17:30:47 +00:00

David Given 4e68af9781 Add a declaration for the -Bxyz module name flag, used by the B compiler.
Rename some of the Basic flags to avoid confusion.

David Given 0e10329876 Fix an issue throughout where B couldn't be built by ackprogram due to symbol
laziness.
2016-12-29 17:11:53 +00:00
David Given a43258fe9d Build the B compiler and standard library (also the Basic one, which was
missing).
2016-12-29 17:11:07 +00:00
David Given ebd424e7f1 First draft of the B module code; a module name can now be specified as a
compiler flag, which is used to set the name of the patch table. The compiler
now understands C preprocessor line directives. Extend the standard library
somewhat.
