David Given ac8edcbfc3 Give up trying to make the B tests pass on CP/M. 2019-06-17 23:33:58 +02:00
David Given 97e6baa052 Fix register corruption when incrementing locals; attempt to solve the 
alignment issue.
 2019-06-17 23:31:54 +02:00
David Given c2f48772e9 Correctly emit \r\n when a \n is written to the console, instead of \n\n... 
Fixes: #198
 2019-06-17 23:31:16 +02:00
David Given 0ecad6c860 Warning fix. 2019-06-17 23:29:41 +02:00
David Given 94867d24b7 Ensure that procedure labels are word aligned (required by the EM spec). 2019-06-17 22:26:31 +02:00
David Given 402468f6fd Bugfix the CP/M FCB parser, and add a test for it. 2019-06-17 00:41:49 +02:00
David Given 97e6d8f66a Update README. 2019-06-16 20:10:13 +02:00
David Given 2b013c34dc Some byte shaving; lseek returns the offset. 2019-06-16 20:04:07 +02:00
David Given 50dca8b954 First at-least-slightly working version of the CP/M read/write stuff. Not as 
bad as I expected, but far too big.
 2019-06-16 19:04:17 +02:00
David Given 3131dc9915 Partially working port of stdio to CP/M. I'm not sure this will work; it's 
getting way too complicated (stdio is horribly subtle). I think I need to
rethink things.
 2019-06-15 22:22:01 +02:00
David Given 9109d7af7f First stage in modularising FILE*. Refactor so that printf/scanf don't rely on 
FILE* innards; allow plats to replace the entire emulated FILE* system.
 2019-06-15 13:07:10 +02:00
David Given 784fc67596 Alignment issues mean we can't access 16-bit CP/M structure elements directly. 2019-06-11 22:33:25 +02:00
David Given 0607529df2 Miscellaneous bugfixed and renamings. 2019-06-11 21:33:57 +02:00
David Given a804375560 Miscellaneous byte shaving; you can now choose whether or not you want the CCP 
overwritten or not, and cpm_exit() does the right thing.
 2019-06-11 20:32:00 +02:00
David Given 3feb79ad0c Simplify the .trp API to make it a bit smaller. 2019-06-11 20:02:03 +02:00

David Given f58d7e7d30 Add missing file. 2019-06-11 19:40:46 +02:00
David Given 48a9c48f56 Generate traps procedurally. For some reason they always keep getting pulled 
in, though...
 2019-06-11 00:12:00 +02:00
David Given ec2ea1feff Add missing file. 2019-06-10 23:57:43 +02:00
David Given d0967e683b Extend the CP/M libsys with a full set of (hopefully correct) 2.2 BDOS calls. 2019-06-10 23:54:23 +02:00
David Given 3f938d651b EM requires 2-alignment in structures, sadly. 2019-06-10 18:33:04 +02:00
George Koehler bec236c108 Include more headers to declare functions. 
This causes clang to give fewer warnings of implicit declarations of
functions.

In mach/pdp/cv/cv.c, rename wr_int2() to cv_int2() because it
conflicts with wr_int2() in <object.h>.

In util/ack, rename F_OK to F_TRANSFORM because it conflicts with F_OK
for access() in <unistd.h>.

George Koehler 84f65f7ce3 Raise _XOPEN_SOURCE from 500 to 700 
In OpenBSD, _XOPEN_SOURCE 500 forces _POSIX_C_SOURCE down to 199506,
which hides the declarations of openat() and fdopendir() and causes
compiler warnings.

Don't set _POSIX_C_SOURCE, because _XOPEN_SOURCE may set
_POSIX_C_SOURCE to a different value.

David Given 79a38ecc08 Instead of using parameterised rsts for stack access, add a huge swathe of 
automatically built helper tools. Star Trek goes up from 40243 to 40779 bytes,
but should be a lot faster.

David Given 7473601172 Add the cpm emulator from Cowgol, modified to work with an 8080 emulator rather 
than libz80ex; enable tests for cpm.
 2019-02-07 22:39:57 +01:00

David Given 1d6ecddcf4 The MIPS backend is still full of holes, and cut-and-pasted PowerPC code, but 
is beginning to look like an actual code generator.
