| | | | | | | | | | | | | | | | | | | | | Retain all CAFs when dynamic Haskell libraries are used from GHCi. The Linker usually replaces references to newCAF with references to newDynCAF, but the system dynamic linker won't do that for us. Also, the situation is slightly different - we never want CAFs from dylibs to be reverted, because the dylibs might be used both by the interpreted program and by GHCi itself. So instead of just caf_list, there's now both caf_list and revertible_caf_list. newDynCAF adds a CAF to revertible_caf_list, and newCAF either adds the CAF to caf_list or to the mutable list, depending on whether we are in GHCi. This hack is only active when Linker.c has loaded libHSbase_dyn.[so|dylib], but for now, it applies to all CAFs, not just dynamically-linked ones. If that is worth fixing, we could do that by checking whether the the CAF closure or it's info pointer is in the main executable's address range. MERGE TO STABLE

| | | | | | include ghcautoconf.h rather than ghcconfig.h, the reason being that this file is included form the compiler, and we don't want the platform defines from ghcplatform.h.

| | | | | | | | | | | Optimisation: the update code only needs to check whether the closure being updated is a BLACKHOLE_BQ if it has been blackholed; which is only the case after lazy blackholing has taken place. So to avoid this unnecessary cost, we have two kinds of update frame: one which checks for BLACKHOLE_BQ and one that doesn't, and the lazy blackholing algorithm converts the latter kind into the former as it replaces thunks with blackholes.

| | | | | | | | | | | | | | | | | | | | | | | GC changes: instead of threading old-generation mutable lists through objects in the heap, keep it in a separate flat array. This has some advantages: - the IND_OLDGEN object is now only 2 words, so the minimum size of a THUNK is now 2 words instead of 3. This saves some amount of allocation (about 2% on average according to my measurements), and is more friendly to the cache by squashing objects together more. - keeping the mutable list separate from the IND object will be necessary for our multiprocessor implementation. - removing the mut_link field makes the layout of some objects more uniform, leading to less complexity and special cases. - I also unified the two mutable lists (mut_once_list and mut_list) into a single mutable list, which lead to more simplifications in the GC.

| | | | | | | | - The output from uncaught exceptions handler is redirected to RTS's errorBelch. - The output from Debug.Trace is redirected to RTS's debugBelch - Usually errorBelch and debugBelch messages go to stderr except for Windows GUI applications. For GUI applications the Debug.Trace output is redirected to debug console and the exceptions message is displayed in message box.

| | | | | | | | Here's a file I forgot to add. NB. ghcconfig.h is now a *source file*. If you're using a linked build tree, please remove it from ghc/includes and re-link (in fact, you probabaly need a make clean in ghc/includes at least).
* [project @ 2005-01-28 12:55:17 by simonmar]simonmar2005-01-2811-72/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rationalise the BUILD,HOST,TARGET defines. Recall that: - build is the platform we're building on - host is the platform we're running on - target is the platform we're generating code for The change is that now we take these definitions as applying from the point of view of the particular source code being built, rather than the point of view of the whole build tree. For example, in RTS and library code, we were previously testing the TARGET platform. But under the new rule, the platform on which this code is going to run is the HOST platform. TARGET only makes sense in the compiler sources. In practical terms, this means that the values of BUILD, HOST & TARGET may vary depending on which part of the build tree we are in. Actual changes: - new file: includes/ghcplatform.h contains platform defines for the RTS and library code. - new file: includes/ghcautoconf.h contains the autoconf settings only (HAVE_BLAH). This is so that we can get hold of these settings independently of the platform defines when necessary (eg. in GHC). - ghcconfig.h now #includes both ghcplatform.h and ghcautoconf.h. - MachRegs.h, which is included into both the compiler and the RTS, now has to cope with the fact that it might need to test either _TARGET_ or _HOST_ depending on the context. - the compiler's Makefile now generates stage{1,2,3}/ghc_boot_platform.h which contains platform defines for the compiler. These differ depending on the stage, of course: in stage2, the HOST is the TARGET of stage1. This was wrong before. - The compiler doesn't get platform info from Config.hs any more. Previously it did (sometimes), but unless we want to generate a new Config.hs for each stage we can't do this. - GHC now helpfully defines *_{BUILD,HOST}_{OS,ARCH} automatically in CPP'd Haskell source. - ghcplatform.h defines *_TARGET_* for backwards compatibility (ghcplatform.h is included by ghcconfig.h, which is included by config.h, so code which still #includes config.h will get the TARGET settings as before). - The Users's Guide is updated to mention *_HOST_* rather than *_TARGET_*. - coding-style.html in the commentary now contains a section on platform defines. There are further doc updates to come. Thanks to Wolfgang Thaller for pointing me in the right direction.

| | | | | | | | | | Instead of defining NO_REGS when IN_STG_CODE==0, define NO_GLOBAL_REG_DECLS instead. This means that in non-STG code we can still get at the values of REG_R1 & co., even though the global register decls are turned off. This is necessary because we sometimes need to set up different stack layouts depending on REG_R1.

| | | | | | | rtsconfig, smrep: fixes to not put info next to code (like ia64) machregs: define registers for powerpc64 - same as ppc32 tailcalls: for now do tailcalls as normal calls. (ok on powerpc since calls don't grow the stack and we don't care about LR anyway)

Other platforms are not yet supported, and there is no support for actually linking or using dynamic libraries - so if you use the -fPIC or -dynamic code generation flags, you have to type your (platform-specific) linker command lines yourself. nativeGen/PositionIndependentCode.hs: New file. Look here for some more comments on how this works. cmm/CLabel.hs: Add support for DynamicLinkerLabels and PIC base labels - for use inside the NCG. needsCDecl: Case alternative labels now need C decls, see the codeGen/CgInfoTbls.hs below for details cmm/Cmm.hs: Add CmmPicBaseReg (used in NCG), and CmmLabelDiffOff (used in NCG and for offsets in info tables) cmm/CmmParse.y: support offsets in info tables cmm/PprC.hs: support CmmLabelDiffOff Case alternative labels now need C decls (see the codeGen/CgInfoTbls.hs for details), so we need to pprDataExterns for info tables. cmm/PprCmm.hs: support CmmLabelDiffOff codeGen/CgInfoTbls.hs: no longer store absolute addresses in info tables, instead, we store offsets. Also, for vectored return points, emit the alternatives _after_ the vector table. This is to work around a limitation in Apple's as, which refuses to handle label differences where one label is at the end of a section. Emitting alternatives after vector info tables makes sure this never happens in GHC generated code. Case alternatives now require prototypes in hc code, though (see changes in PprC.hs, CLabel.hs). main/CmdLineOpts.lhs: Add a new option, -fPIC. main/DriverFlags.hs: Pass the correct options for PIC to gcc, depending on the platform. Only for powerpc for now. nativeGen/AsmCodeGen.hs: Many changes... Mac OS X-specific management of import stubs is no longer, it's now part of a general mechanism to handle such things for all platforms that need it (Darwin [both ppc and x86], Linux on ppc, and some platforms we don't support). Move cmmToCmm into its own monad which can accumulate a list of imported symbols. Make it call cmmMakeDynamicReference at the right places. nativeGen/MachCodeGen.hs: nativeGen/MachInstrs.hs: nativeGen/MachRegs.lhs: nativeGen/PprMach.hs: nativeGen/RegAllocInfo.hs: Too many changes to enumerate here, PowerPC specific. nativeGen/NCGMonad.hs: NatM still tracks imported symbols, as more labels can be created during code generation (float literals, jump tables; on some platforms all data access has to go through the dynamic linking mechanism). driver/mangler/ghc-asm.lprl: Mangle absolute addresses in info tables to offsets. Correctly pass through GCC-generated PIC for Mac OS X and powerpc linux. includes/Cmm.h: includes/InfoTables.h: includes/Storage.h: includes/mkDerivedConstants.c: rts/GC.c: rts/GCCompact.c: rts/HeapStackCheck.cmm: rts/Printer.c: rts/RetainerProfile.c: rts/Sanity.c: Adapt to the fact that info tables now contain offsets. rts/Linker.c: Mac-specific: change machoInitSymbolsWithoutUnderscore to support PIC.

| | | | | | | | Use some sed magic to avoid PACKAGE_FOO clashes introduced by the autoconf cleanup yesterday. Another option would have been using a plain "AC_INIT" in fptools/configure.ac (and probably the same for fptools/libraries/configure.ac), so only "leaf configure.ac"s have package info. Not quite sure what would be the nicest way to handle this yet...
