LegalizeTypes support for EXTRACT_VECTOR_ELT.  The
approach taken is different to that in LegalizeDAG
when it is a question of expanding or promoting the
result type: for example, if extracting an i64 from
a <2 x i64>, when i64 needs expanding, it bitcasts
the vector to <4 x i32>, extracts the appropriate
two i32's, and uses those for the Lo and Hi parts.
Likewise, when extracting an i16 from a <4 x i16>,
and i16 needs promoting, it bitcasts the vector to
<2 x i32>, extracts the appropriate i32, twiddles
the bits if necessary, and uses that as the promoted
value.  This puts more pressure on bitcast legalization,
and I've added the appropriate cases.  They needed to
be added anyway since users can generate such bitcasts
too if they want to.  Also, when considering various
cases (Legal, Promote, Expand, Scalarize, Split) it is
a pain that expand can correspond to Expand, Scalarize
or Split, so I've changed the LegalizeTypes enum so it
lists those different cases - now Expand only means
splitting a scalar in two.

16 years agoLegalizeTypes support for legalizing the mask
Duncan Sands [Wed, 27 Feb 2008 13:03:44 +0000 (13:03 +0000)]
LegalizeTypes support for legalizing the mask
operand of a VECTOR_SHUFFLE.  The mask is a
vector of constant integers.  The code in
LegalizeDAG doesn't bother to legalize the
mask, since it's basically just storage for
a bunch of constants, however LegalizeTypes
is more picky.  The problem is that there may
not exist any legal vector-of-integers type
with a legal element type, so it is impossible
to create a legal mask!  Unless of course you
cheat by creating a BUILD_VECTOR where the
operands have a different type to the element
type of the vector being built...  This is
pretty ugly but works - all relevant tests in
the testsuite pass, and produce the same
assembler with and without LegalizeTypes.

While hunting for two hanging tests,

(on solaris10, which are:
  CodeGen/PowerPC/frounds.ll
  Transforms/InstCombine/2008-02-23-MulSub.ll)

I needed a tool to figure out which one is the guilty.

To this end I have added a verbosity
option to the test/Makefile.

It can be invoked thus:

gmake check TESTSUITE=CodeGen/PowerPC VERBOSE="-v -v"

(The number of "-v"s specifies the verbosity level.
 Instead of "-v" other aliases can be specified,
 please consult the dejagnu docs for info.)

At level >= 2 following line is logged for each
test, before running it:

Fix a nasty bug in LegalizeTypes (spotted in
CodeGen/PowerPC/illegal-element-type.ll): suppose
a node X is processed, and processing maps it to
a node Y.  Then X continues to exist in the DAG,
but with no users.  While processing some other
node, a new node may be created that happens to
be equal to X, and thus X will be reused rather
than a truly new node.  This can cause X to
"magically reappear", and since it is in the
Processed state in will not be reprocessed, so
at the end of type legalization the illegal node
X can still be present.  The solution is to replace
X with Y whenever X gets resurrected like this.
