65610ec774 gitlab-ci: Add ppc64el and s390x cross-build jobs
Using LLVM 8 for ppc64el and 7 for s390x (which hits some coroutine
related issues with LLVM 8).

There are some test failures we need to ignore for now. Also, the
timeout needs to be bumped from the default 30s for some tests, because
they can take longer under emulation.

1496cc92f6 util/hash_table: added hash functions for integer types
A few hash_table users roll their own integer hash functions which
call _mesa_hash_data to perform the hashing which ultimately calls
into XXH32 with a dynamic key length. When using small keys with a
constant size the hash rate can be greatly improved by inlining
XXH32 and providing it a constant key length, see:
https://fastcompression.blogspot.com/2018/03/xxhash-for-small-keys-impressive-power.html

Additionally, this patch removes calls to _mesa_key_hash_string and
makes them instead call _mesa_has_string directly, matching the new
integer hash functions.

This will allow us to continue searching the current path for

a999798daa meson: Add tests to suites
Meson test has a concepts of suites, which allow tests to be grouped
together. This allows for a subtest of tests to be run only (say only
the tests for nir). A test can be added to more than one suite, but for
the most part I've only added a test to a single suite, though I've
added a compiler group that includes nir, glsl, and glcpp tests.

To use this you'll need to invoke meson test directly, instead of ninja
test (which always runs all targets). it can be invoked as:
`meson test -C builddir --suite $suitename` (meson test has addition
options that are pretty useful).

   #ifdef NOT_DEFINED
   #define A_MACRO(x) \

this then gets recognised as #if.

Until 28a3731e3f this didn't happen because we ended up in
<HASH>{NONSPACE} where BEGIN INITIAL was called stopping the
problem from happening.

This change makes sure we never call RETURN_TOKEN_NEVER_SKIP for

ff0ce31e2a python: Disable universal newlines
We are testing the behaviour of a tool, for different input files, each
one using a different newline sequence. ('\n' on UNIX, '\r\n' on
Windows, …)

Unfortunately, when opening a file in text mode, Python 3 will by
default enable the "universal newlines" mode, which means it replaces
all the known newline sequences by '\n'.

This (usually useful) behaviour breaks the tests, which are specifically
trying to handle files with newline sequences different from '\n'.

Disabling the universal newlines mode fixes the tests.

However, to keep the script compatible with both Python 2 and 3, we must
use the io.open() function instead of the open() builtin, as the latter
only knows about the `newline` argument on Python 3.

f0cdc39b13 meson: remove dependency antipattern
`dep_valgrind != []` now (0.45) produces a warning that is quite explicit:
  WARNING: Trying to compare values of different types (DependencyHolder, list) using !=.
  The result of this is undefined and will become a hard error in a future Meson release.

`dep_valgrind = []` used to be the recommended way to deal with
non-existant dependency, but these don't work with `.found()`, so now
the recommended way is to declare a impossible dependency, which
null_dep does for us in Mesa.

In short, we don't need and shouldn't check for `!= []` anywhere anymore.

1ff1dc1c63 glsl/glcpp: Handle hex constants with 0X prefix
GLSL 4.6 spec describes hex constant as:

hexadecimal-constant:
    0x hexadecimal-digit
    0X hexadecimal-digit
    hexadecimal-constant hexadecimal-digit

Right now if you have a shader with the following structure:

    #if 0X1 // or any hex number with the 0X prefix
    // some code
    #endif

the code between #if and #endif gets removed because the checking is performed
only for "0x" prefix which results in strtoll being called with the base 8 and
after encountering the 'X' char the strtoll returns 0. Letting strtoll detect
the base makes this limitation go away and also makes code easier to read.

From the strtoll Linux man page:

"If base is zero or 16, the string may then include a "0x" prefix, and the
number will be read in base 16; otherwise, a zero base is taken as 10 (decimal)
unless the next character is '0', in which case it is taken as 8 (octal)."

This matches the behaviour in the GLSL spec.

This patch also adds a test for uppercase hex prefix.

f7741985be glcpp: fix #undef to match latest spec update and GLSLang implementation
GLSL ES spec includes the following:

   "It is an error to undefine or to redefine a built-in
    (pre-defined) macro name."

But desktop GLSL doesn't. This has sparked some discussion
in Khronos, and the final conclusion was to update the
GLSL 4.50 spec to include the following:

   "By convention, all macro names containing two consecutive
    underscores ( __ ) are reserved for use by underlying
    software layers.  Defining or undefining such a name in a
    shader does not itself result in an error, but may result
    in unintended behaviors that stem from having multiple
    definitions of the same name.  All macro names prefixed
    with “GL_” (“GL” followed by a single underscore) are also
    reserved, and defining or undefining such a name results in
    a compile-time error."

In other words, undefining GL_* names should be an error, but
undefining other names with a double underscore in them is
not strictly prohibited in desktop GLSL.

This patch fixes the preprocessor to apply these rules,
following exactly the implementation already present
in GLSLang. This fixes some tests in CTS.

4a47247523 glcpp: Skip unnecessary line continuations removal
Overwhelming majority of shaders don't use line continuations. In my
shader-db only shaders from the Talos Principle and Serious Sam used
them, less than 1% out of all shaders. Optimize for this case, don't
do any copying if no line continuation was found.

b8e792ee25 glcpp: Avoid unnecessary strcmp()
strcmp() is slow. Initiate comparison with "__LINE__" or "__FILE__"
only if the identifier starts with '_', which is rare.
