David Given d2c14ca44f Precisely one stack hreg gets allocated for each vreg/congruence group for
eviction; this prevents us from having to worry about moving values from stack
slot to stack slot, which is hard.

David Given b7a1c96986 MIPS appears to hate converting unsigneds to floats and vice versa. 2018-09-05 23:53:38 +02:00
David Given fc0b0ae178 (Slightly) better errors on phi congruence group mismatches. 2018-09-05 23:53:08 +02:00
David Given 7fbce066f8 We attempt to compile the first library function; we fail. 2018-09-05 00:13:01 +02:00
David Given 26fe3f7530 Added library skeletons. 2018-09-05 00:07:07 +02:00
David Given 98afb42095 Added a boot.o based on the PowerPC one. 2018-09-05 00:00:13 +02:00
David Given 26c0228b14 The examples all compile now (probably incorrectly, and the libc doesn't
compile yet).
2018-09-04 23:55:28 +02:00
David Given 9d80756253 Lots of assembler and rule bugfixing. 2018-09-04 23:43:24 +02:00

David Given 83cf1be6a8 mcgg now checks that registers have at most one type attribute set. 2018-09-03 22:03:57 +02:00
David Given f8e71d888b Add some painfully untested FPU instructions. 2018-09-02 21:36:09 +02:00
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.
2018-09-02 18:57:25 +02:00
David Given a023fd8591 Better error reporting for unterminated strings. 2018-09-02 18:55:44 +02:00

Fix warnings and convert the Modula-2 library to ANSI C.
2018-06-25 22:29:47 +02:00
David Given 7971bdba5a Warning-fixed and ansified the Modula-2 library. 2018-06-25 22:22:37 +02:00
David Given f8ba7ef962 Move the Modula-2 library includes into a directory in lang/m2 where they belong. 2018-06-24 20:32:59 +02:00

Merge pull request #109 from davidgiven/dtrg-warnings
Rework the Linux include directories.
2018-06-24 20:03:21 +02:00
David Given ab7002c0ee All the Linux include directories are the same, so common them all out into a
single one, like OSX.

Merge pull request #107 from davidgiven/dtrg-libc
OpenBSD fixes
2018-06-24 00:21:29 +02:00
David Given bbb98240fe Merge from trunk. 2018-06-24 00:08:39 +02:00
David Given f45b357740 Remove the dependency on the glibc-only byteswap.h. 2018-06-24 00:01:06 +02:00
David Given 1fc20e90c0 Remove c99-isms. 2018-06-23 23:56:34 +02:00
David Given 205c8d0a35 Run through clang-format. 2018-06-23 23:46:44 +02:00

Merge pull request #106 from davidgiven/dtrg-libc
Refactor the libc
2018-06-23 23:28:21 +02:00
David Given fd94e219d4 Remove the attic. 2018-06-23 23:16:22 +02:00
David Given 59dbdea48a Move mktemp to sys; attic getgrent as noone will ever use this. 2018-06-23 23:15:42 +02:00
David Given 3f10299f43 Move the portable time code into core. clock() goes into sys (as it calls
times()).
2018-06-23 19:49:29 +02:00
David Given 64ae1d7583 Move time() into sys; change the name of the variable which controls it. 2018-06-23 19:40:50 +02:00
David Given bb78fd158c Move the big gnarly functions like system() and popen() into sys, and make them
build.
2018-06-23 19:18:16 +02:00
David Given 6a729b846a Move stdio into (mostly) sys. 2018-06-23 18:54:40 +02:00
David Given af22b7ea85 Change stdio to use atexit() rather than the internal __clean variable; this
breaks the dependency between exit/atexit and stdio. Buffers are no longer
flushed on abort() (because it's pretty risky). Move the relevant functions
into sys/core.
2018-06-23 18:35:45 +02:00
David Given f744a21699 All the opendir()/readdir() stuff is obsolete because it's all implemented in
terms of open() and read(), which isn't how it's done any more; move the
functions into an attic.
2018-06-23 18:25:26 +02:00
David Given df1cdf7762 Add the sys directory for libc functions which use system calls; move the
malloc functions in there.
2018-06-23 18:08:03 +02:00
David Given c4e4505a73 Move the errno functions into core. 2018-06-23 17:52:15 +02:00
David Given 538eefb573 Get em22 working. Remove the leading-underscore system calls from its libsys. 2018-06-23 15:57:57 +02:00
David Given 74d166ef9a Get the pdp7 plat working; remove the leading-underscore syscalls. 2018-06-23 15:18:26 +02:00
David Given 3e40374297 Made the rpi platform work with the new libc layout. 2018-06-23 13:05:27 +02:00
David Given dbb2062d03 Made pc86 work with the new libc. 2018-06-23 12:59:40 +02:00
David Given 680b4071b7 Made the two OSX platforms work with the new libc layout. 2018-06-23 12:55:59 +02:00
David Given b727b7affd Make linuxppc work. 2018-06-23 12:41:54 +02:00
David Given b267b56ad9 Made linux68k work; commoned up all the generic linux includes. 2018-06-23 12:35:17 +02:00
David Given 66815ff987 Make linux386 work with the new libc layout. 2018-06-23 12:13:33 +02:00
David Given 32c881474e Create a basic and probably wrong common unistd.h, which replaces the plat one.
Made this work with cpm (but nothing else yet).
2018-06-23 11:46:55 +02:00
David Given dd0f959245 Move assert into core. 2018-06-23 11:16:06 +02:00
David Given fe3951d4ae Warning fix. 2018-06-23 11:14:49 +02:00
David Given fac0764621 Don't crash and burn if there are no tests to run. 2018-06-23 11:14:40 +02:00
