Bob Wilson 074436b090 Get Neon intrinsic names from the new "Name" field in the tblgen records
instead of just converting the record name to lowercase.

llvm-svn: 120809
2010-12-03 17:19:39 +00:00
Bob Wilson e6b421ccb5 Add support for "_lane" variants of VMUL, VMLA, and VMLS Neon intrinsics.

2010-12-03 00:34:12 +00:00
Bob Wilson 791934e122 Support using macros for Neon intrinsics implemented without builtins.
Intrinsics implemented with Clang builtins could already be implemented as
either inline functions or macros, but intrinsics implemented directly
(without builtins) could only be inline functions.

2010-12-03 00:34:09 +00:00
Bob Wilson 4375586bd9 Simplify code in Neon intrinsics. No functional changes intended.
For most intrinsics, there is no need to allocate a temporary to hold the
result value; just return it directly.

Bob Wilson 79026235e6 Assign arguments of Neon intrinsic macros to local temporaries.
Since we're casting them for the calls to the builtins, we need this to
make sure their types get checked in the same way they would if the intrinsics
were implemented as inline functions.

llvm-svn: 120693
2010-12-02 07:10:39 +00:00
Bob Wilson 014fe01ac8 Use statement expressions in Neon intrinsics defined as macros.
This is in preparation for adding assignments to temporaries to ensure
that the proper type checking is done.

llvm-svn: 120649
2010-12-02 02:42:51 +00:00
Bob Wilson 492de6da40 Add casts for splatted scalars in calls to Neon builtins.
llvm-svn: 120641
2010-12-02 01:18:23 +00:00
Bob Wilson ec626b09cb Add a missing cast for Neon vsbl results.
The bitwise operations are always done with unsigned values, but the result may
be signed.

llvm-svn: 120640
2010-12-02 01:18:20 +00:00
Bob Wilson c08944fd5a Add another missing cast for Neon vcombine results.
llvm-svn: 120639
2010-12-02 01:18:18 +00:00
Bob Wilson a9ea9ef840 Add casts in arm_neon.h for result values in inline functions as well as macros.
We should not rely on lax-vector-conversions for these intrinsics to work.

llvm-svn: 120638
2010-12-02 01:18:15 +00:00
Bob Wilson 743eeae937 Avoid "char" for Neon vector elements; make it explicitly signed (or unsigned).
llvm-svn: 120632
2010-12-02 00:24:59 +00:00
Bob Wilson be764f0cd1 Cast scalar results of Neon macros to the correct type.
llvm-svn: 120631
2010-12-02 00:24:56 +00:00

llvm-svn: 120595
2010-12-01 19:49:51 +00:00
Bob Wilson b91ae1ac52 Fix copy-and-paste error in exception message.
llvm-svn: 120033
2010-11-23 19:38:34 +00:00
Bob Wilson 4e22a38759 Change the 'x' type modifier for Neon intrinsics to force a signed integer.
This makes it symmetric with the 'u' modifier that forces an unsigned type.
This is needed for unsigned vector shifts, where the shift amount still needs
to be signed.  PR8482 (Radar 8603521).

llvm-svn: 119742
2010-11-18 21:43:22 +00:00

Bob Wilson 0045702afe Refactor to new GetNumElements function.
No functional change.

Bob Wilson dfac58bed1 Tidy up some things in <arm_neon.h>.
Stop defining types with "__neon_" prefixes and then using typedefs without
the prefix; there's no reason to do that anymore.  Remove types that combine
multiple Neon vectors and treat them as a single long vector; they are not
used.

Bob Wilson 02d6467291 Use float64 instead of int64 vector elements for NEON vget_low and vget_high
functions, since int64 is not a legal type and using it leads to inefficient
code.  PR8036.
