* Produce new-style Cmm from the Cmm parserSimon Marlow2012-10-081-289/+288
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main change here is that the Cmm parser now allows high-level cmm code with argument-passing and function calls. For example: foo ( gcptr a, bits32 b ) { if (b > 0) { // we can make tail calls passing arguments: jump stg_ap_0_fast(a); } return (x,y); } More details on the new cmm syntax are in Note [Syntax of .cmm files] in CmmParse.y. The old syntax is still more-or-less supported for those occasional code fragments that really need to explicitly manipulate the stack. However there are a couple of differences: it is now obligatory to give a list of live GlobalRegs on every jump, e.g. jump %ENTRY_CODE(Sp(0)) [R1]; Again, more details in Note [Syntax of .cmm files]. I have rewritten most of the .cmm files in the RTS into the new syntax, except for AutoApply.cmm which is generated by the genapply program: this file could be generated in the new syntax instead and would probably be better off for it, but I ran out of enthusiasm. Some other changes in this batch: - The PrimOp calling convention is gone, primops now use the ordinary NativeNodeCall convention. This means that primops and "foreign import prim" code must be written in high-level cmm, but they can now take more than 10 arguments. - CmmSink now does constant-folding (should fix #7219) - .cmm files now go through the cmmPipeline, and as a result we generate better code in many cases. All the object files generated for the RTS .cmm files are now smaller. Performance should be better too, but I haven't measured it yet. - RET_DYN frames are removed from the RTS, lots of code goes away - we now have some more canned GC points to cover unboxed-tuples with 2-4 pointers, which will reduce code size a little.

* Deprecate lnat, and use StgWord insteadSimon Marlow2012-09-071-4/+4
| | | | | | | | | | | | lnat was originally "long unsigned int" but we were using it when we wanted a 64-bit type on a 64-bit machine. This broke on Windows x64, where long == int == 32 bits. Using types of unspecified size is bad, but what we really wanted was a type with N bits on an N-bit machine. StgWord is exactly that. lnat was mentioned in some APIs that clients might be using (e.g. StackOverflowHook()), so we leave it defined but with a comment to say that it's deprecated.

| * Fix GHCi segfault during startup on linux-powerpc (#2972).Erik de Castro Lopo2012-08-131-4/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Slightly modified version of a patch from Ben Collins <bcollins@ubuntu.com> who did the final debugging that showed the segfault was being caused the memory protection mechanism. Due to the requirement of "jump islands" to handle 24 bit relative jump offsets, GHCi on PowerPC did not use mmap to load object files like the other architectures. Instead, it allocated memory using malloc and fread to load the object code. However there is a quirk in the GNU libc malloc implementation. For memory regions over certain size (dynamic and configurable), malloc will use mmap to obtain the required memory instead of sbrk and malloc's call to mmap sets the memory readable and writable, but not executable. That means when GHCi loads code into a memory region that was mmapped instead of malloc-ed and tries to execute it we get a segfault. This solution drops the malloc/fread object loading in favour of using mmap and then puts the jump island for each object code module at the end of the mmaped region for that object. This patch may also be a solution on other ELF based powerpc systems but does not work on darwin-powerpc.

* Tell checkProddableBlock how many bytes we want to writeIan Lynagh2012-05-011-18/+23
| | | | | | | | | It doesn't suffice for checkProddableBlock to just check whether the largest possible write could be made at the address we are writing, as if we are making a smaller write then checkProddableBlock may conservatively think we will write off the end of the block. Thus we now tell checkProddableBlock how many bytes we will write.

| | | | | | | | | | | | | | | | | | | | | | | Add support for ELF objects on ARM to the runtime linker.
