This isn't necessarily the best approach, but the most obvious

Use the SubclassData field to hold ExtType, isTrunc, and MemIndexedMode
information. This eliminates the need for the Flags field in MemSDNode,
so this makes LoadSDNode and StoreSDNode smaller. Also, it makes
FoldingSetNodeIDs for loads and stores two AddIntegers smaller.

Dan Gohman [Tue, 3 Feb 2009 00:04:43 +0000 (00:04 +0000)]
Change Feature64Bit to not imply FeatureSSE2. All x86-64 hardware has
SSE2, however it's possible to disable SSE2, and the subtarget support
code thinks that if 64-bit implies SSE2 and SSE2 is disabled then
64-bit should also be disabled. Instead, just mark all the 64-bit
subtargets as explicitly supporting SSE2.

Also, move the code that makes -march=x86-64 enable 64-bit support by
default to only apply when there is no explicit subtarget. If you
need to specify a subtarget and you want 64-bit code, you'll need to
select a subtarget that supports 64-bit code.
