Explicitly allow the argument to --with-dri-drivers to contain
comma-separated or space-separated drivers. A space-separated driver
list worked by chance before.
Currently the installation directories for libraries and headers are
resolved within the install commands. For instance, the libraries will
be installed to $(INSTALL_DIR)/$(LIB_DIR). This limits the flexibility
of the installation, such as when the libraries should be installed to a
subdirectory like /usr/lib/tls.
This adds the make variables $(INSTALL_LIB_DIR) and $(INSTALL_INC_DIR)
to define the locations that the libraries and headers are installed.
For the static configs, this resolves exactly as before to
$(INSTALL_DIR)/include and $(INSTALL_DIR)/$(LIB_DIR). For autoconf, they
are derived directly from the --libdir and --includedir settings.
Use the common facilities to convert non-native instructions into native ones.
Worked hard to make the code easier to read (hopefully), by using helper
functions instead of direct manipulation of the machine code.
Fixes two bugs related to FLR and XPD.
The old behaviour depended on which texture images the fragment program
reads from, which seems to contradict the shader specifications.
Note: Piglit's general/texgen test checks for this problem.
If the 'shader' parameter is wrong, need to either generate GL_INVALID_VALUE
or GL_INVALID_OPERATION. It depends on whether 'shader' actually names a
'program' or is a totally unknown ID.
There might be other cases to fix...
This fixes a failure for cases like:
vec4 v;
v[1] *= 2.0;
The v[1] actually acts like a writemask, equivalent to v.y
The fix is a bit convoluted, but will do for now.
Before, the presence of a 'return' statement always prevented inlining
a function. This was because we didn't want to accidentally return from
the _calling_ function. We still need the semantic of 'return' when inlining
but we can't always use unconditional branches/jumps (GPUs don't always
support arbitrary branching).
Now, we allow inlining functions w/ return if the return is the last
statement in the function. This fixes the common case of a function
that returns a value, such as:
vec4 square(const in vec4 x)
{
return x * x;
}
which effectively compiles into:
vec4 square(const in vec4 x)
{
__retVal = x * x;
return;
}
The 'return' can be no-op'd now and we can inline the function.
