This seems to be the shortest path to getting Delay working. It's kind
of playing with fire, hence the warning, but it does seem to work if
you're careful.

Another option that I considered was to use dlmopen() to put libEGL into
its own link map (and thus own TLS scope). That doesn't work because of
dlmopen bugs, and wouldn't be portable outside of glibc and Solaris.

Another another option I consider was to add a new GLDISPATCH_API_BLAH
enum and teach the frontend libraries to handle it. This got ugly
quickly, in part because I think that ends up wanting additional API
between the frontend and vendor library without having a good way to
signal from the frontend that that API is available. So if we're adding
API anyway, simply exporting one function we already have seems quite a
bit simpler.

Fix some duplicate code in configure.ac

See merge request glvnd/libglvnd!232

Combine the x86/x86-64 and stub type selection branches, since the same code
works for either of them.

In configure.ac, there's a block that should have been moved to later in the
file, but got copied instead. Remove the leftover duplicate.

build: Support meson-0.49.2

See merge request glvnd/libglvnd!230

Ternary operator inside method call crashes the parser,
so it's relocated outside.

This change will help to build project under latest debian:10

Remove -Werror from default CFLAGS

See merge request glvnd/libglvnd!229

The set of warnings emitted are dependent on compiler version,
optimization level, CPU architecture, dependency versions, etc. It's not
tractable for a code base to be warning free under all circumstances,
and it's widely agreed that -Werror should not be enabled by default.

Given that it's trivial for developers to enable -Werror for autotools
by settings CFLAGS=-Werror and for meson with -Dwerror=true we should
not enable -Werror by default and require builders to disable it.

See https://devmanual.gentoo.org/ebuild-writing/common-mistakes/index.html#-werror-compiler-flag-not-removed



Reviewed-by: Eric Anholt <eric@anholt.net>

The next commit will remove -Werror from the default autotools and meson
builds, but we would like to continue treating warnings as errors in CI.

generate: Use xml.etree.ElementTree instead of cElementTree.

Closes #204

See merge request glvnd/libglvnd!227

The cElementTree module is deprecated as of 3.3, so use the normal ElementTree
module instead.

Fixes glvnd/libglvnd#204

meson: Treat warnings as errors.

See merge request glvnd/libglvnd!226

In the Meson build, treat warnings as errors like we do in the autotools build.

egl: sync with Khronos

See merge request glvnd/libglvnd!225

Updated the EGL headers and XML file to the Khronos repository, from commit
90b78b0662e2f0548cfd1926fb77bf628933541b.

x86: Add ENDBR at function entries

Intel Control-flow Enforcement Technology (CET):

https://software.intel.com/en-us/articles/intel-sdm

contains shadow stack (SHSTK) and indirect branch tracking (IBT). When
CET is enabled, ELF object files must be marked with .note.gnu.property
section. Also when IBT is enabled, all indirect branch targets must
start with ENDBR instruction which is NOP on non-CET processors.

This fixes:

tests: Remove an include for GL/glxint.h.

On PA-RISC, the _GLOBAL_OFFSET_TABLE_ symbol is always exposed. See

Meson: Add datadir and datarootdir variables to libglvnd.pc.

Add the missing datadir and datarootdir variables to the libglvnd.pc file that
Meson generates.

Use xvfb-run in CI scripts

See merge request glvnd/libglvnd!212

GL/glxint.h isn't a standard GLX header, and isn't needed for anything, so just
remove it.

When building for armel, Meson's cpu() and cpu_family() strings aren't always
sufficient.

Instead, try to check for some predefined macros to determine if it's building
for ARMv7 or something older.

Change the CI scripts to use xvfb-run instead of running Xvfb directly.

That avoids a potential race condition, where a test could fail because Xvfb
hasn't started listening for connections yet. xvfb-run will wait for Xvfb to be
ready before it runs any other programs.

That also simplifies error handling, because the CI scripts can just use
"set -e" instead of having to store the exit code, kill Xvfb, and then check
for an error.
