Chris Lattner 446548d2a3 update this entry, now that Anton implemented shift/and lowering for 
switches.  There is one really easy isel thing here with tst we are not
getting.

Evan Cheng 9aa5fc8577 Opcode modifier s comes after condition code. e.g. addlts, not addslt.

Chris Lattner 3e3ff30aa2 Fix the asmprinter so that a globalvalue can specify an explicit alignment 
smaller than the preferred alignment, but so that the target can actually
specify a minimum alignment if needed.  This fixes some objc protocol
failures Devang tracked down.

Evan Cheng 19eeee41ca For VFP2 fldm, fstm instructions, the condition code is printed after the address mode and size specifier. e.g. fstmiaseq, not fstmeqias.

 2007-05-29 23:34:19 +00:00
Evan Cheng a6e9a4ce07 For ldrb, strh, etc., the condition code is before the width specifier. e.g. streqh, not strheq.

Dale Johannesen f9cbdc676c name change requested by review of previous patch 
llvm-svn: 37289
 2007-05-22 18:31:04 +00:00
Dale Johannesen 82810c8a13 Make tail merging the default, except on powerPC. There was no prior art 
for a target-dependent default with a command-line override; this way
should be generally usable.

Bill Wendling 3fb7fdfded We only need to specify the most-implied feature for an architecture.

Evan Cheng 147b334b6a BlockHasNoFallThrough() now returns true if block ends with a return instruction; AnalyzeBranch() should ignore predicated instructionsd.

Evan Cheng 4ae1840d21 Mark calls non-predicable for now. Need to ensure it's the last instruction in the if-converted block or make sure it preserve condition code.

Dale Johannesen 58698d2534 More effective breakdown of memcpy into repeated load/store. These are now 
in the order lod;lod;lod;sto;sto;sto which means the load-store optimizer
has a better chance of producing ldm/stm.  Ideally you would get cooperation
from the RA as well but this is not there yet.
