Running minstall directly means that /bin/sh is always used as hte
interpreter. If the user needs or wants to use a different shell fo
minstall, they can use the SHELL make variable.
Most make implementations will use /bin/sh as the interpreter for
commands and only use a different shell when the $(SHELL) make variable
is set. This makes the setting explicit and allows $(SHELL) to be used
in the commands themselves.
Establish the shell that make will use from configure. This is exactly
how autoconf/automake operate, with the environment variable
CONFIG_SHELL respected to override the autoconf checks. In the usual
case where the user just executes `./configure', autoconf will pick a
shell from the current shell, sh, bash, ksh or sh5 that meets its base
criteria.
The special Solaris case of looking for a POSIX shell has been changed
to just set the SHELL variable since autoconf substitutes this already.
The EXTRA_CONFIG_LINES substitution is dropped as it should no longer be
needed.
When an input is marked in gl_program.InputsRead but is not actually read
in the final program (due to dead-code elimination or whatever), the order
of input registers must still match gl_program.InputsRead. This is done
even more explicitly now.
Use an abstracted instruction scheduling and register allocation algorithm
that we will be able to share with r300_fragprog.
Unlike the original emit code, this code tries to pair instructions that
only use the RGB part of the ALU with instructions that only use the alpha
part. However, the pairing algorithm still has some shortcomings;
for example, it doesn't generate optimal code for the emulation of LIT.
The documentation in autoconf.html is much more explicit about how the
different configure options control the build. This adds a notice at the
end of the `./configure --help' output to tell the user about it.
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.
