Recommited r156374 with critical fixes in BitcodeReader/Writer:
Ordinary patch for PR1255.
Added new case-ranges orientated methods for adding/removing cases in SwitchInst. After this patch cases will internally representated as ConstantArray-s instead of ConstantInt, externally cases wrapped within the ConstantRangesSet object.
Old methods of SwitchInst are also works well, but marked as deprecated. So on this stage we have no side effects except that I added support for case ranges in BitcodeReader/Writer, of course test for Bitcode is also added. Old "switch" format is also supported.

Jakob Stoklund Olesen [Thu, 10 May 2012 23:27:10 +0000 (23:27 +0000)]
Compute secondary sub-registers.

The sub-registers explicitly listed in SubRegs in the .td files form a
tree. In a complicated register bank, it is possible to have
sub-register relationships across sub-trees. For example, the ARM NEON
double vector Q0_Q1 is a tree:

  Q0_Q1 = [Q0, Q1],  Q0 = [D0, D1], Q1 = [D2, D3]

But we also define the DPair register D1_D2 = [D1, D2] which is fully
contained in Q0_Q1.

This patch teaches TableGen to find such sub-register relationships, and
assign sub-register indices to them. In the example, TableGen will
create a dsub_1_dsub_2 sub-register index, and add D1_D2 as a
sub-register of Q0_Q1.

This will eventually enable the coalescer to handle copies of skewed
sub-registers.

12 years agoUse the cpuid 64 bit flag to pick the default CPU name for an unknown model.

Use the cpuid 64 bit flag to pick the default CPU name for an unknown model.

For the Family 6 switch in sys::getHostCPUName, an unrecognized model was
reported as "i686".  That's a really bad default since it means that new
CPUs will be treated as if they can only use 32-bit code.  This just looks
at the cpuid extended feature flag for 64 bit support, and if that is set,
it uses a default x86-64 cpu.  Similar logic is already used for the Family
15 code.  <rdar://problem/11314502>
