New patches: [update documentation John Meacham **20100710060720 Ignore-this: c8d8dfb0370e612d87e1e498056f93dc ] addfile ./docs/announce-0.7.4.txt addfile ./docs/dependency_format.mkd hunk ./docs/announce-0.7.4.txt 1 +Announcing jhc 0.7.4! There have been a few major changes, the main one being +that there is now support for a garbage collector. This drastically increases +the number of programs which are feasable to compile with jhc. + + http://repetae.net/computer/jhc/ + +Any testing people can do with -fjgc would be greatly appreciated! My gameplan +is to fix any issues that come up with the new gc and release a 0.7.5 that +will have the GC enabled by default. This will probably be the first version +of jhc I can recommend to non-developers with a good concience :). Once that is +done I can implement a good strategy for library compatibility with other +compilers and the standards. As it is, jhc has a mix of haskell 98 and haskell +2010 and the ghc base as its distributed libraries, basically whatever I found I +needed in practice I added as I went along. This won't work in the long run. + +Major changes + + * a garbage colletor which can be enabled with '-fjgc' is available. + after some more testing, I will make it the default in the 0.7.5 release. + * A new memory allocator based on Jeff Bonwick's slab memory allocator for + kernels. This means that in many cases, memory can be pulled off a slab + and immediately used with no initialization, in addition, it allowed a + rearrangement of the GC meta-data to optimizally use the cache. + * packed representation of algebraic types, 'Maybe Foo' is actually + represented in memory as a NULL pointer or just a 'Foo' with no tag bits. + Combined with the slab allocator, this can double the number of some common + values that can be put in a cache line. + * some intense profiling of generated code and modification of the rts and + code generator. Signifigant speed-ups in compiled programs are the result. + +Some other changes since 0.7.3 are + * documentation updates, especially when it comes to the runtime. + * ghc 6.12 support (it is in fact required now.) + * no more monolithic 'Main'. the core pass moved to E.Main and the grin pass + moved to Grin.Main. + * generated C code is more compact and easier to debug. + * more use of bytestring internally, improved performance + * JHC_RTS_INCLUDE flag allows including the rts from an + external file. useful for debugging/developing the RTS. + * explicit register support in grin, for alternate back ends such as a NCG + * Removed all compiler magic dealing with Eq,Bounded,Ord, and Bits. instances + for these are specified in haskell code even for built in types now. + * cleaned out some obsolete flags and options on command line. + * updated applicative and support for newest version of 'containers' library. + * bug updates + * various bug fixes hunk ./docs/dependency_format.mkd 1 +{-#Using + +# Dependency Information + +Jhc can output dependency information describing how source files and libraries +depend on each other while compiling code. The dependency information is +generated when the --deps name.yaml option is passed to jhc. It is presented in the +standard YAML format and its fields are as described below. + + - LibraryDeps: the libraries that are dependend on. It is a hash of library ids to the specific filename of the library used. + - LibraryDesc: if building a library, this field contains the name of the library description file used. + - ModuleDeps: a hash of module names to the list of modules that are directly dependend on by said module. + - ModuleSouce: a hash of module name to the haskell source file used.
