* progs/trivial: test case for dlist statechange eliminationKeith Whitwell2009-06-302-0/+170
| | | | | | Creates a display list with redundant call to glShadeModel. View dlist contents with MESA_VERBOSE=list
* mesa/dlist: restore missing SAVE_FLUSH_VERTICES in save_ShadeModelKeith Whitwell2009-06-301-0/+1
| | | | | Reorganization of ShadeModel to avoid flushing vertices too often ended up never flushing vertices due to omitted line of code.
* mesa/vbo: use _lookup_prim_by_nr for debuggingKeith Whitwell2009-06-304-4/+4
| | | | Switch over to specialized enum lookup for primitives
* mesa: add debug printer for primitive nameKeith Whitwell2009-06-302-0/+28
| | | | | | Add a simple version of _mesa_lookup_enum_by_nr() which expects a primitive enum (GL_POINTS..GL_POLYGON). This avoids some annoying duplicates when looking up primitives, such as the GL_FALSE/GL_POINTS clash.
* progs/glsl: link with GLEW libraryBrian Paul2009-06-301-1/+1

* mesa/dlist: shortcircuit some redundant statechanges at compile timeKeith Whitwell2009-06-302-19/+51
| | | | | | | | | | | | | | | | | | | | | | | Currently, state-changes in mesa display lists are more or less a verbatim recording of the GL calls made during compilation. This change introduces a minor optimization to recognize and eliminate cases where the application emits redundant state changes, eg: glShadeModel( GL_FLAT ); glBegin( prim ) ... glEnd() glShadeModel( GL_FLAT ); glBegin( prim ) ... glEnd() The big win is when we can eliminate all the statechanges between two primitive blocks and combine them into a single VBO node. This commit implements state-change elimination for Material and ShadeModel only. This is enough to make a start on debugging, etc.
* progs/util: make sure function pointers are initializedKeith Whitwell2009-06-291-1/+6
| | | | | Call Init() from CompileShaderFile, was previously only called for the Text version of this function.
* progs/glsl: compile with scons and glewKeith Whitwell2009-06-2927-1/+106
| | | | Get most of these working with scons.
* scons: Don't raise an exception when DXSDK is not found.José Fonseca2009-06-291-5/+3
| | | | | Unfortunately scons does not check if a tool exists before it invokes its generate function.
* scons: Disable optimizations only for gcc-4.2José Fonseca2009-06-281-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gcc-4.2's optimizer has a strange bug where it looses code from inner loops in certain situations. For example, if the appearently innocent looking code below is compiled with gcc-4.2 -S -O1, the inner loop's code is missing from the outputed assembly. struct Size { unsigned width; }; struct Command { unsigned length; struct Size sizes[32]; }; extern void emit_command(void *command, unsigned length); void create_surface( struct Size size, unsigned faces, unsigned levels) { struct Command cmd; unsigned face; unsigned level; cmd.length = faces*levels*sizeof(cmd.sizes[0]); for(face = 0; face < faces; ++face) { for(level = 0; level < levels; ++level) { cmd.sizes[face*levels + level] = size; // This should generate a shrl statement, but the whole for body // disappears in gcc-4.2 -O1/-O2/-O3! size.width >>= 1; } } emit(&cmd, sizeof cmd.length + cmd.length); } Note that this is not specific to MinGW's gcc-4.2 crosscompiler (the version typically found in debian/ubuntu's mingw32 packages). gcc-4.2 on Linux also displays the same error. gcc-4.3 and above gets this correctly though. Updated MinGW debian packages with gcc-4.3 are available from http://people.freedesktop.org/~jrfonseca/debian/pool/main/m/
* scons: Use -Bsymbolic linker option.José Fonseca2009-06-281-0/+5
| | | | | | | | This prevents the error relocation R_X86_64_PC32 against symbol `_gl_DispatchTSD' can not be used when making a shared object; recompile with -fPIC when building on x86_64 architecture.
* docs: detect when too many varying vars are usedmesa_7_5_rc4Brian Paul2009-06-261-0/+1

* glsl: check number of varying variables against the limitBrian Paul2009-06-261-4/+9
| | | | | | Link fails if too many varying vars. (cherry picked from master, commit cc58fbcf2c5c88f406818db60910f537e03610d6)

|
* mesa: raise MAX_VARYING (number of shader varying vars) to 16Brian Paul2009-06-261-1/+1
| | | | | | 16 is the limit for now because of various 32-bit bitfields. (cherry picked from master, commit 4e762395ef7e8c332c16fd0c11025cfa52763a45)
* intel / DRI2: Additional flush of fake front-buffer to real front-bufferIan Romanick2009-06-261-0/+11
| | | | | | | | | | | To maintain correctness, the server will copy the real front-buffer to a newly allocated fake front-buffer in DRI2GetBuffersWithFormat. However, if the DRI2GetBuffersWithFormat is triggered by glViewport, this will copy stale data into the new buffer. Fix this by flushing the current fake front-buffer to the real front-buffer in intel_viewport. Fixes bug #22288.

| | | | | | | A new node type (SLANG_OPER_RETURN_INLINED) is used to denote 'return' statements inside inlined functions which need special handling. All glean glsl1 tests pass for EmitContReturn=FALSE and TRUE.

| | | | | | | | Need to execute the for loop's increment code before we continue. Add a slang_assemble_ctx::CurLoopOper field to keep track of the containing loop and avoid the "cont if true" path in this situation. Plus, assorted clean-ups.
