* glsl: add new interpolateAt* builtin functionsChris Forbes2014-07-121-0/+67
| | | | | | | | | | | | V2: - Don't assume everyone wants interpolateAtSample() lowered to interpolateAtOffset. It turns out this isn't what we want most of the time for i965. Lowering can be added later in an ir pass which drivers opt into, rather than bolting it straight into the builtin definition. - Only expose the interpolateAt* builtins in the fragment language.

* allow builtin functions to require parameters to be shader inputsChris Forbes2014-07-122-0/+24
| | | | | | | | | | | | | The new interpolateAt* builtins have strange restrictions on the <interpolant> parameter. - It must be a shader input, or an element of a shader input array. - It must not include a swizzle.

* radeonsi: properly implement texture opcodes that take an offsetMarek Olšák2014-07-111-84/+104
| | | | | | | | | | | | Instead of using intr_name in lp_build_tgsi_action, this selects the names with a switch statement in the emit function. This allows emitting llvm.SI.sample for instructions without offsets and llvm.SI.image.sample.*.o otherwise. This depends on my LLVM changes. When LLVM 3.5 is released, I'll switch all texture instructions to the new intrinsics.

| | | | | | | | | | | | Before, we were checking the level against view->u.tex.last_level but level is not valid for buffers. Plus, the aliasing of the view->u.tex view->u.buf members (a union) caused the level checking arithmetic to be totally wrong. The net effect is we always returned early for PIPE_BUFFER size queries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GLSL ES Specification 3.00.4 says: #if, #ifdef, #ifndef, #else, #elif, and #endif are defined to operate as for C++ except for the following: ... • Undefined identifiers not consumed by the defined operator do not default to '0'. Use of such identifiers causes an error. [Page 11 (page 127 of the PDF file)] as well as: The semantics of applying operators in the preprocessor match those standard in the C++ preprocessor with the following exceptions: • The 2nd operand in a logical and ('&&') operation is evaluated if and only if the 1st operand evaluates to non-zero. • The 2nd operand in a logical or ('||') operation is evaluated if and only if the 1st operand evaluates to zero. If an operand is not evaluated, the presence of undefined identifiers in the operand will not cause an error. (Note that neither of these deviations from C++ preprocessor behavior apply to non-ES GLSL, at least as of specfication version 4.30.6). The first portion of this, (generating an error for an undefined macro in an (short-circuiting to squelch errors), was not implemented previously, but is implemented in this commit. A test is added for "make check" to ensure this behavior. Note: The change as implemented does make the error message a bit less precise, (it just states that an undefined macro was encountered, but not the name of the macro).

* glsl/glcpp: Fix glcpp to properly lex entire "preprocessing numbers"Carl Worth2014-07-093-0/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The preprocessor defines a notions of a "preprocessing number" that starts with either a digit or a decimal point, and continues with zero or more of digits, decimal points, identifier characters, or the sign symbols, ('-' and '+'). Prior to this change, preprocessing numbers were lexed as some combination of OTHER and IDENTIFIER tokens. This had the problem of causing undesired macro expansion in some cases. We add tests to ensure that the undesired macro expansion does not happen in cases such as: #define e +1 #define xyz -2 int n = 1e; int p = 1xyz; In either case these macro definitions have no effect after this change, so that the numeric literals, (whether valid or not), will be passed on as-is from the preprocessor to the compiler proper. This fixes the following Khronos GLES3 CTS tests: preprocessor.basic.correct_phases_vertex preprocessor.basic.correct_phases_fragment v2. Thanks to Anuj Phogat for improving the original regular expression, (which accepted a '+' or '-', where these are only allowed after one of [eEpP]. I also expanded the test to exercise this. v3. Also fixed regular expression to require at least one digit at the beginning (after an optional period). Otherwise, a string such as ".xyz" was getting sucked up as a preprocessing number, (where obviously this should be a field access). Again, I expanded the test to exercise this.
