Evan Cheng 0d782b4c60 Doh. Must check if GV is constant first.

Anton Korobeynikov 41a83d7871 Do section switching right way for Mingw\Cygwin and Linux. 
This will allow (after llvm-gcc linkage fix) more dummy tests using
libstdc++ to pass on mingw :)

llvm-svn: 31120
 2006-10-22 21:37:13 +00:00
Anton Korobeynikov 24b7ac303c Fixed mingw\cygwin linkonce linkage once again. 
Added workaround for linker bug with linkonce sections.
Changed sections prefix to allow linker merge them
(PE loader doesn't like too much long-named sections :) )
All of this unbreaks libstdc++ on mingw32 allowing (small)
programs to be compiled, linked and run.

Anton Korobeynikov d61d39ec53 Adding dllimport, dllexport and external weak linkage types. 
DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

Chris Lattner d0201946ad Fix the MASM asmprinter's lies. It does not want to emit code to .text/.data 
it wants it emitted to _text/_data.

Owen Anderson 20a631fde7 Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference. 
This fixes PR 759.

Nate Begeman 287dc5be0d Hooray, everyone now uses the same printBasicBlockLabel implementation 
llvm-svn: 28056
 2006-05-02 17:34:51 +00:00
Nate Begeman b9d4f8324d Extend printBasicBlockLabel a bit so that it can be used to print all 
basic block labels, consolidating the code to do so in one place for each
target.

Nate Begeman 4ca2ea5b43 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.
