 2010-11-16 18:34:07 +00:00
Rafael Espindola 46c79ef113 Fix PR8565. 
This moves most of the isUsed logic to the MCSymbol itself. With this we
get a bit more relaxed about allowing definitions after uses: uses that
don't evaluate their argument immediately (jmp foo) are accepted.

ddunbar, this was the smallest compromise I could think of that lets us
accept gcc (and clang!) assembly.

llvm-svn: 119144

 2010-11-11 18:13:52 +00:00
Rafael Espindola 9bb44a5ce8 Fixed version of 118639 with an extra assert to catch similar problems

Rafael Espindola 8aefb66376 Improvements to .section parsing: 
* If we have a M or a G, reject sections without the type
* Only parse the flag specific arguments if we have M or G
* Parse the corresponding arguments for M and G

We ignore the G arguments and flag for now.

Pointed out by Chris!

 2010-10-27 18:45:20 +00:00
Rafael Espindola eb0c2c170d Add support for the .symver directive. This is really ugly, but most of it is 
contained in the ELF object writer.

llvm-svn: 117448

Kevin Enderby a68d004d88 Incorporate suggestions by Daniel Dunbar after his review. Thanks Daniel! 
1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better
   named.  Since it is just a predicate and isn't actually changing any state.

2) Added a missing return in the comments for setCurrentDwarfLoc() in 
   include/llvm/MC/MCContext.h for fix formatting.

3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change
   state.

4) Simplified the last test in isValidDwarfFileNumber() to just a one line
   boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement.

Jan Wen Voung 87f77b5f9a Add hook in MCSection to decide when to use "optimized nops", for each 
section kind. Previously, optimized nops were only used for MachO.
Also added tests for ELF and COFF.

Kevin Enderby e46564a4a8 This is the last major patch to implement support for the .loc directive 
and output the dwarf line number tables.  This contains the code to emit and
encode the dwarf line tables from the previously gathered information in the
MCLineSection objects.  This contains all the details to encode the line and
address deltas into the dwarf line table.

To do this an MCDwarfLineAddrFragment has been added.

Also this moves the interface code out of Mach-O streamer into
MCDwarf so it should be useable by other object file formats.

There is now one call to be made from an MCObjectStreamer
EmitInstruction() method:
   MCLineEntry::Make(this, getCurrentSection());
to create a line entry after each instruction is assembled.

And one call call to be made from an MCObjectStreamer Finish() method:
   MCDwarfFileTable::Emit(this, DwarfLineSection);
when getContext().hasDwarfFiles() is true and is passed a object file specific
MCSection where to emit the dwarf file and the line tables.

This appears to now be correct for 32-bit targets, at least x86.  But the
relocation entries for 64-bit Darwin needs some further work which is next
up to work on.  So for now the 64-bit Mach-O target does not output the
dwarf file and line tables.

Jan Wen Voung b96b2d8e4d Have ELFAsmParser.cpp use the already parsed "Size" (entry size) when 
constructing a section. Test for a few cases also included.

Chris Lattner b44fd24fc1 change the protocol TargetAsmPArser::MatchInstruction method to take an 
MCStreamer to emit into instead of an MCInst to fill in.  This allows the
matcher extra flexibility and is more convenient.
