2013-07-19Implement generic upsample()Aaron Watry4-0/+61
Reduces all vector upsamples down to its scalar components, so probably not the most efficient thing in the world, but it does what the spec says it needs to do. Another possible implementation would be to convert/cast everything as unsigned if necessary, upsample the input vectors, create the upsampled value, and then cast back to signed if required.

2013-07-16Fix and re-enable R600 vload/vstore assemblyAaron Watry5-56/+233
The assembly optimizations were making unsafe assumptions about which address spaces had which identifiers. Also, fix vload/vstore with 64-bit pointers. This was broken previously on Radeon SI. This version still only has assembly versions of int/uint 2/4/8/16 for global loads and stores on R600, but it does it in a way that would be very easily extended to private/local/constant and could also be handled easily on other architectures. v2: 1) Leave v[load|store]_impl.ll in generic/lib 2) Remove vload_if.ll and vstore_if.ll interfaces 3) Fix address+offset calculations 3) Remove offset from assembly arg list git-svn-id: https://llvm.org/svn/llvm-project/libclc/trunk@186416 91177308-0d34-0410-b5e6-96231b3b80d8

This commit gets us back to pure CLC and fixes offset calculations. The next commit will re-enable the assembly implementation for R600, fix bugs related to 64-bit address spaces, and also fix the incorrect assumption that address space identifiers are the same in all architectures. git-svn-id: https://llvm.org/svn/llvm-project/libclc/trunk@186415 91177308-0d34-0410-b5e6-96231b3b80d8

libclc was defining and undefing GENTYPE and several other macros with common names in its header files.

2013-06-26libclc: Add assembly versions of vstore for global [u]int4/8/16Tom Stellard4-6/+168
The assembly should be generic, but at least currently R600 only supports 32-bit stores of [u]int1/4, and I believe that only global is well-supported.

Squashed commit of the following: commit a0df0a0e86c55c1bdc0b9c0f5a739e5adef4b056 Author: Aaron Watry <awatry@gmail.com> Date: Mon Apr 15 18:42:04 2013 -0500 libclc: Rename clz.ll to clz_if.ll to ensure it gets built. configure.py treats files that have the same name with the .cl and .ll extensions as overriding eachother. E.g. If you have clz.cl and clz.ll both specified to be built in the same SOURCES file, only the first file listed will actually be built. Since the contents of clz.ll were an interface that is implemented in clz_impl.ll, rename clz.ll to clz_if.ll to make sure that the interface is built. commit 931b62bed05c58f737de625bd415af09571a6a5a Author: Aaron Watry <awatry@gmail.com> Date: Sat Apr 13 12:32:54 2013 -0500 libclc: llvm assembly implementation of clz Untested... currently crashes in the same manner as add_sat. commit 6ef0b7b0b6d2e5584086b4b9a9243743b2e0538f Author: Aaron Watry <awatry@gmail.com> Date: Sat Mar 23 12:35:27 2013 -0500 libclc: Add stub clz builtin For scalar int/uint, attempt to use the clz llvm builtin.. for all others return 0 until an actual implementation is finished.

2013-06-26libclc: Add clamp(vec, scalar, scalar) and max(vec, scalar)Tom Stellard4-0/+20
For any GENTYPE that isn't scalar, we need to implement a mixed vector/scalar version of clamp/max. This depends on the min() patches I sent to the list a few minutes ago. Patch by: Aaron Watry git-svn-id: https://llvm.org/svn/llvm-project/libclc/trunk@185003 91177308-0d34-0410-b5e6-96231b3b80d8

2013-06-26libclc: Rename [add|sub]_sat.ll to [add|sub]_sat_if.llTom Stellard4-2/+4
configure.py allows overloading *.cl with *.ll, but will only ever build the first file listed in SOURCES of ${file}.cl and ${file}.ll add_sat, sub_sat, (and the soon to be submitted clz) all define interfaces in ${function_name}.ll which are implemented in ${function_name}_impl.ll. Renaming the interface files is enough to get them to build again, fixing CL usage of these functions. Tested on clover/r600g.

This implementation does a lot of bit shifting and masking.
