Removed use of dyn_cast, llvm no compiles
without exceptions and rtti by
default. We do need exceptions for the libconfig stuff, but rtti isn't
necessary (anymore).
Debug info needs to be rewritten, as in LLVM 2.7 the format has
completely changed. To have something to look at while rewriting, the
old code has been wrapped inside #ifndef DISABLE_DEBUG_INFO , this means
that you have to define this to compile at the moment.
Updated tango 0.99.9 patch to include updated EH runtime code, which is
needed for LLVM 2.7 as well.
* remove an #ifdef USE_METADATA I accidently left in
* remove now unneeded llvm-version includes
* fix indentation in metadata.h
* prevent the "Found native target" message from interrupting ccmake
`available_externally` linkage. This allows the inliner to inline functions from
other modules while telling the code generator to ignore those functions (treat
them as declarations)
Still generates a few extra `TypeInfo`s and strings...
Disabled when generating debug info because I don't really understand it, and it
doesn't like this.
Fixed problem with DtoConstSize_t taking a size_t argument, this is not enough for cross compiling from 32bit host to a 64bit target. It now takes uint64_t. There's probably a lot of similar case around to code ...
Added -v-cg switch, which right now just prints "codegen: module.name (module/name.d)" to stdout, this can really help figuring out where, in some complex build command, things go wrong.
other special cases.
(for example: this shouldn't be done if the symbol in question is also nested
in a template; such symbols should get template-like linkage)
In particular, %.nest_arg is always aligned even though it's bitcast from i8*.
Pointers in vtables are also guaranteed to be stored at aligned addresses.
Also moved the #defines for linkage types into a separate header instead of
mars.h so we can #include revisions.h without having to rebuild the entire
frontend every time we update.
(I'm using revisions.h to get the LLVM revision for use in preprocessor
conditionals. It should work with LLVM release 2.5, old trunk and new trunk)
llvm::OStream provides all std::ostream functionality (by holding a
std::ostream* internally), but
* doesn't include <iostream>, avoiding per-file overhead.
* allows the stream pointer to be null, and the (inlined) operators do nothing
when that's the case. (This also allows removal of the ofstream("/dev/null")
hack Logger used when disabled, which presumably wasn't very portable)
- Moved main() into its own file gen/main.cpp
- Fixed basic cross compilation
- removed the option for setting OS
- added support for llc's mattr, mcpu and mtriple switches
- added basic ABI abstraction for return value rewrites, it's not perfect and will probably be completely rewritten once I get to handling parameter rewrites as well.
- x86-64 extern(C) abi for cfloat returns now match (llvm-)gcc.
Applied patch from ticket #129 to compile against latest LLVM. Thanks Frits van Bommel.
Fixed implicit return by asm block at the end of a function on x86-32. Other architectures will produce an error at the moment. Adding support for new targets is fairly simple.
Fixed return calling convention for complex numbers, ST and ST(1) were switched around.
Added some testcases.
I've run a dstress test and there are no regressions. However, the runtime does not seem to compile with symbolic debug information. -O3 -release -inline works well and is what I used for the dstress run. Tango does not compile, a small workaround is needed in tango.io.digest.Digest.Digest.hexDigest. See ticket #206 .
Fixed align N; in asm blocks.
Fixed inreg parameter passing on x86 for ref/out params.
Removed support for lazy initialization of function local static variables, I have no idea why I ever implemented this, it's not in the D spec, and DMD doesn't support it :P
Some of the global variable related changes might cause minor regressions, but they should be easily fixable.
