5 years agopython: Specify the JSON separators
Mathieu Bridon [Wed, 27 Jun 2018 10:37:39 +0000 (12:37 +0200)]
python: Specify the JSON separators

On Python 2, the default JSON separators are ', ' for items and ': ' for
dicts.

On Python 3, the default is the same when no indent is specified, but if
one is (and we do specify one) then the default items separator becomes
',' (the dict separator remains unchanged).

This change explicitly specifies the Python 3 default, which helps
ensuring that the output is identical, whether it was generated by
Python 2 or 3.

i965: Fix output register sizes when variable ranges are interleaved

In 6f5abf31466aed this code was fixed to calculate the maximum size of
an attribute in a seperate pass and then allocate the registers to
that size. However this wasn’t taking into account ranges that overlap
but don’t have the same starting location. For example:

layout(location = 0, component = 0) out float a[4];
layout(location = 2, component = 1) out float b[4];

Previously, if ‘a’ was processed first then it would allocate a
register of size 4 for location 0 and it wouldn’t allocate another
register for location 2 because it would already be covered by the
range of 0. Then if something tries to write to b[2] it would try to
write past the end of the register allocated for ‘a’ and it would hit
an assert.

This patch changes it to scan for any overlapping ranges that start
within each range to calculate the maximum extent and allocate that
instead.
