Chris Lattner a8fbbc0ec3 Print float constants as 4 byte values. 
Also, fix endianness problems when cross compiling from little-endian host.

 2004-08-17 02:48:44 +00:00
Chris Lattner bc9372bf77 Make sure to put an _ prefix on all identifiers! 
Also, add some (currently disabled) code to print float's as 32-bits.

Start using the AsmPrinter base class to factor out a bunch of code

llvm-svn: 15840
 2004-08-16 23:25:21 +00:00
Chris Lattner 9cf46456cb Start using the AsmPrinter to emit our first class constants. This also 
drops our half-assed support for cygwin, which noone uses and doesn't work
anyway.

llvm-svn: 15808
 2004-08-16 02:12:49 +00:00
Nate Begeman dabf0a52c0 Fix frame pointer handling: 
Reserve R0 in store/load from stack slot for building >32k offsets from SP
or FP.  This also requires we use R11 rather than R0 for holding the LR
value we want to save or restore.  Also, tell the register allocator not
to use R31 (our FP) in functions that have a frame pointer.  These changes
fix Burg.

llvm-svn: 15807

Chris Lattner 7dfaac4300 Zimm16 is now dead. Its entry is not removed from the enum, to avoid having 
to renumber everything.  Similar elimination should be applied to other
operand enum values that are only used to format printing in the .s file.

llvm-svn: 15755
 2004-08-15 05:48:47 +00:00
