It really ought to be autoconfed (current settings suits an x86/gcc). Makefile updated to include HsFFI.h machdep.c prelude.h Int64 support static.c type.c parser.y input.c storage.c storage.h connect.h New syntax and related frontend changes. ffi.c Tweak code generator to match changes. Extend with many new ffi-supported types builtin.c iomonad.c plugin.c Runtime support. Big change is addition of HugsAPI4 and associated operations. This extends HugsAPI3 (greencard support) in the usual way. Note: I'd like to eliminate all direct greencard support and do a big cleanup ASAP. There's a lot of accumulated cruft in there.

cvs commit: hugs98/lib/exts Storable_aux.c
by Alastair Reid 14 Jun '02

14 Jun '02

reid 2002/06/14 07:25:48 PDT Added files: lib/exts Storable_aux.c Log: Support code for Storable.hs - defines teh read/writeFooOffPtr functions. In writing this code, some attempt was made to make it easier to cut and paste definitions so that it would be easier to generate the missing definitions. It'd probably be easier to use the more obvious technique of using cpp to do the job.

cvs commit: hugs98/lib/exts CTypes.hs FunPtr.hs MarshalAlloc.hs MarshalArray.hs MarshalError.hs MarshalUtils.hs Ptr.hs StablePtr.hs Storable.hs
by Alastair Reid 14 Jun '02

14 Jun '02

reid 2002/06/14 07:19:29 PDT Added files: lib/exts CTypes.hs FunPtr.hs MarshalAlloc.hs MarshalArray.hs MarshalError.hs MarshalUtils.hs Ptr.hs StablePtr.hs Storable.hs Log: First of a series of commits of the new ffi code. Existing uses of GreenCard-generated code should still work (and seems to do so). These are enough of the libraries to run some tests. Some of them (notably CTypes.hs and Storable.hs) are very incomplete _and_ should (but aren't) be configured with autoconf and should (but isn't) be built from the sources in the hierarchial library archive. I'd love it if someone were to tackle either of these problems before I get to them.

cvs commit: hugs98/src machdep.c
by Alastair Reid 12 Jun '02

12 Jun '02

reid 2002/06/12 11:55:25 PDT Modified files: src machdep.c Log: Fixed dynamic loading implementation for Darwin. Tweaked the code to use a fresh namespace for each loaded module instead of the global namespace. This means that when you lookup _initModule you get a different answer each time. What was happening before was you always got the first _initModule loaded into the namespace which was always the one from StdDIS.so so we kept initializing StdDIS instead of initializing the module we'd just loaded. Someone who knows Darwin better should check this code over. My source of documentation was some random web page instead of a proper manual. My testcase was an X program being run on a machine on which I couldn't run X - so all I know is that it loads successfully but I can't say for sure that it runs ok.

cvs commit: hugs98/tests Readme testScript.in
by Alastair Reid 12 Jun '02

12 Jun '02

reid 2002/06/12 09:55:11 PDT Modified files: tests Readme testScript.in Log: Yesterday's fixes to the testScript were scrogged because.... I forgot that you have to commit testScript not testScript.in While I was in there I fixed the header on testScript.in which should read: CONTEXT_DIFF='@CONTEXT_DIFF@' export CONTEXT_DIFF DEV_NULL='@DEV_NULL@' export DEV_NULL HUGSFLAGS=-P../lib:../lib/hugs:../lib/exts export HUGSFLAGS HUGS=../src/hugs Hmmm, maybe the right thing to do is for configure to make a little config script containing nothing but the above and for testScript to source that file. This'd avoid screwups like yesterday. Revision Changes Path 1.5 +3 -0 hugs98/tests/Readme 1.20 +88 -88 hugs98/tests/testScript.in
