V3D only has one of these (the top 16 bits of a float32) left in its CLs,
but VC4 had many more. This gets us proper pretty-printing of the values
instead of a large uint.
Python 2 has a range() function which returns a list, and an xrange()
one which returns an iterator.
Python 3 lost the function returning a list, and renamed the function
returning an iterator as range().
As a result, using range() makes the scripts compatible with both Python
versions 2 and 3.

It turns out that most V3D versions change very few packets, so keeping
separate copies of the XML per version makes changing the XML a pain as
you have to replicate your changes to each one. This is the start of
changing it so that one XML can generate headers for multiple versions.
Right now, we name these fields as "field name minus one" so that your C
code obviously states what the value should be. However, it's easy enough
to handle at the codegen level with another little XML attribute, meaning
less C code and easier-to-read values in CLIF dumping and gdb as well.
(The actual CLIF format for simulator and FPGA replay takes in
pre-minus-one values, so we need it there too).
You'd need src/broadcom/cle/ in the -I previously, for srcdir != builddir.
nir was fine at that, but automake didn't have it.
Bugzilla: https://github.com/anholt/mesa/issues/104
We try to emit a #error and continue so that you can debug the missing
type at C compile time, but were missing a couple of definitions in that
path (sigh, python).
For enums we were doubling the underscore if the value had a numeric first
character of its name (which safe_name() adds an underscore to). A little
helper function cleans up the other instance of prefixing while also
fixing this.
We were handing the intra-byte padding fine, but with a 24-bit address
(bottom 8 bits implied 0) we would end up off by 8 bytes in our shift,
impacting vc5's load/store general packets (all other packets we have had
<8 bits of padding).
In the vc5 NIR backend, I want to use the XML code-generation to set up
pack/unpack of structs for the texture uniforms, and setting up the
unpacked copy needs a default header.
I really liked this idea, as it should help with management of packet
parsing tools like the CL dump. The python script is forked off of theirs
because our packets are byte-based instead of dwords, and the changes to
do so while avoiding performance regressions due to unaligned accesses
were quite invasive.
v2: Fix Android.mk paths, drop shebang for python script, fix overlap
detection.
