HSAIL backend changes
Contributed-by: Tom Deneau <tom.deneau@amd.com>
* stackslot mapping was incorrect when combinations of 32-bit and
64-bit stores were generated. StackSlot alignment in
HSAILTargetDescription set to 8.
* compressedOops support in various heap size configurations (with or
without either of shift or heap base). So we don't need
XX:-UseCompressedOops anymore.
* some support for unsigned shifts, long shifts, logical ops for long
datatype.
* a new GraalOption, InlineEverything. Some HSAIL targets are not
able to handle HSAIL function calls yet, plus we are still working
on emitting HSAIL function calls in the compiler.
* hack for emitForeignCall special cases of createOutOfBoundsException
or createNullPointerException. (We just emit a comment. Real
exception handling still pending). These nodes came about when we
more aggressively inlined, although this has not been explained yet.
* support HSAILAddressValues as operands for arithmetic ops. Use
HSAIL lda instruction to get address into a register. Used in
particular for USHR for card-marking.
* Added some new junit tests. (some ported from their lambda versions)
* StaticNBodyCallTest which would fail with default inlining (since
we don't yet generate HSAIL calls). It uses junit.assumeTrue and
tests whether InlineEverything is set. It (and also some
lambda-based junit tests not part of this webrev) do pass nicely
when InlineEverything is set true.
* tests for storing an object, which test being able to handle the
card-marking logic, as well as the encoding and decoding of a
compressed oop.
* some 2D matrix tests that showed a problem before the stackslot
change above. (have a mixture of 32-bit and 64-bit stackslot
spills)
