* add a note about how we should implement this FIXME from the legalizer:Chris Lattner2006-01-281-1/+1
| | | | | | | | // FIXME: revisit this when we have some kind of mechanism by which targets // can decided legality of vector constants, of which there may be very // many. llvm-svn: 25733
* add an option to generate completely non-pic code, corresponding to whatChris Lattner2005-11-171-0/+6
| | | | | | | | | | | | | gcc -static produces on PPC. This is used for building kexts and other things. With this, materializing the address of a global looks like: lis r2, ha16(L_H$non_lazy_ptr) la r3, lo16(L_H$non_lazy_ptr)(r2) we're still emitting stubs for functions, which is wrong. That is next. llvm-svn: 24399
* Allow itineraries to be passed through the Target Machine.Jim Laskey2005-11-011-0/+1

* Give full control of subtarget features over to table generated code.Jim Laskey2005-10-261-9/+12

* Do the right thing and enable 64 bit regs under the control of a subtargetNate Begeman2005-10-181-0/+3
| | | | | | | option. Currently the only way to enable this is to specify the 64bitregs mattr flag. It is never enabled by default on any config yet. llvm-svn: 23779
* Rename PowerPC*.h to PPC*.hChris Lattner2005-10-141-2/+2

* On non-apple systems, when using -march=ppc32, do not print:Chris Lattner2005-09-071-1/+1
| | | | | | | | '' is not a recognized processor for this target (ignoring processor) Default to "generic" instead of "" for the default CPU. llvm-svn: 23257
* Add accessor for 64bit flag, so that we can tell when it is safe toNate Begeman2005-09-061-0/+1

* Add help support for -mcpu and -mattr.Jim Laskey2005-09-021-21/+27

* Decouple fsqrt from gpul optimizations, implementing fsqrt.ll.Chris Lattner2005-09-021-7/+4
| | | | | | Remove the -enable-gpopt option which is subsumed by feature flags. llvm-svn: 23218
* 1. Use SubtargetFeatures in llc/lli.Jim Laskey2005-09-011-10/+82
| | | | | | | | 2. Propagate feature "string" to all targets. 3. Implement use of SubtargetFeatures in PowerPCTargetSubtarget. llvm-svn: 23192
* Consolidate the GPOpt stuff to all use the Subtarget, instead of stillChris Lattner2005-08-051-10/+27
| | | | | | | | depending on the command line option. Now the command line option just sets the subtarget as appropriate. G5 opts will now default to on on G5-enabled nightly testers among other machines. llvm-svn: 22688
* Enable gp optimizations by default when available, even when a target tripleChris Lattner2005-08-051-0/+3
| | | | | | | is available, since the target triple doesn't specify whether to use gpopts or not. llvm-svn: 22685
