Rafael Espindola fdc88137f4 Remove AllowQuotesInName and friends from MCAsmInfo. 
Accepting quotes is a property of an assembler, not of an object file. For
example, ELF can support any names for sections and symbols, but the gnu
assembler only accepts quotes in some contexts and llvm-mc in a few more.

LLVM should not produce different symbols based on a guess about which assembler
will be reading the code it is printing.

Joerg Sonnenberger 62f759791a Be nice to Xcore and the XMOS assembler and avoid quoting section names 
that contain only letters, digits and the characters "_" and ".".

Rafael Espindola 70d8015063 Switch llvm to using comdats. For now always use groups with a single 
section.

Rafael Espindola 9bb44a5ce8 Fixed version of 118639 with an extra assert to catch similar problems 
earlier. Implicit bool -> int conversions are evil!

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.

Jan Wen Voung efbdbe5565 Move logic of determining ELF entsize from the .s printer to initialization 
time. That way, the EntrySize field is initialized for other code paths, 
namely, the .ll -> .o code path.

Chris Lattner e9a75a6654 rename TAI -> MAI, being careful not to make MAILJMP instructions :)

Chris Lattner 0fbe0f51a4 add support for target-specific ELF section flags, add a new MCSectionXCore 
class which represents the XCore cp/dp section flags.  No functionality
change yet.

Dan Gohman 3e0bd7852f Fix MCSectionELF::ShouldOmitSectionDirective's matching of .data and 
friends so that it doesn't match sections like .data.rel.local, which
should not be emitted as section directives.

Bruno Cardoso Lopes 62e6a8bbe6 Remove HasCrazyBSS and add a flag in TAI to indicate that '.section' 
must be emitted for PowerPC-Linux '.bss' section

 2009-08-13 21:08:56 +00:00
Bruno Cardoso Lopes 607cd3b63a Change MCSectionELF to represent a section semantically instead of 
syntactically as a string, very similiar to what Chris did with MachO.
The parsing support and validation is not introduced yet.
