It looks like we were ignoring -linker when -noprefix wasn't present, and
when -noprefix was present, -linker was mandatory and -cplusplus ignored.

Teach mklib/minstall more about cygwin so libraries are properly installed

Have mklib install the .dll into the lib/ staging directory as well

Have minstall install the .dll into PREFIX/bin at the same time as
installing the .dll.a link library into PREFIX/lib

mklib uses a '-' rather than a '.' as the separator before the version
number in library names on cygwin.  Change the install globs so they match
library names like that.

Change mklib not to report the full archname when building a library for cygwin
(which is something like 'CYGWIN_NT-5.1' or 'CYGWIN_NT-6.1-WOW64' and kind of
confusing), but just 'CYGWIN'.

The GLSL 1.20 spec specifically disallows this, but it was allowed in
GLSL 1.10.

Fixes piglit test cases local-function-0[13].frag and bugzilla #29921.

This fixes fbo-3d and fbo-cubemap

This reverts commit de0b76cab22caa9fc7260f80acb8f151ccced6c5, its pre-computes the texture state wrong,

you can't just use an array of levels, since you can have FBOs to depth texture slices inside a level as well
it would get really messy quickly. Probably need to split commits like this up into pieces for each piece
of state, so we can revert bits easier in case of regressions.

This also break 5 piglit tests, and valgrind starts to warn about invalid read/writes after this.

fixes warning that
r600_blit.c: In function ‘r600_resource_copy_region’:
r600_blit.c:136: warning: passing argument 1 of ‘util_resource_copy_region’ from incompatible pointer type

and also 7 more piglit tests.

add cube and shadow support to the texture code.

This, plus the previous commit fix fd.o bug 29806.

When x==0, the result was wrong.  Fixes piglit glsl-fs-atan-1.shader_test

Both i965 and swrast rely on UsesKill to determine whether to do early
depth writes.  Fixes glsl-fs-discard-02.

Bug #29835.

Make two passes over the constructor parameters.  Write all of the
constants in a single write, then write the non-constants one at a
time.  This causes the fragment shader

varying float g;
void main()
{
	gl_FragColor = vec4(0.0, g, 0.0, 1.0);
}

to generate

(function main
  (signature void (parameters )
    (
      (declare (temporary ) vec4 vec_ctor@0x8580058)
      (assign (constant bool (1)) (xzw) (var_ref vec_ctor@0x8580058)  (constant vec4 (0.000000 0.000000 0.000000 1.000000)) )
      (assign (constant bool (1)) (y) (var_ref vec_ctor@0x8580058)  (swiz xxxx (var_ref g@0x8580218) ))
      (assign (constant bool (1)) (xyzw) (var_ref gl_FragColor@0x84d32a0)  (var_ref vec_ctor@0x8580058) )
    ))
)

instead of

(function main
  (signature void (parameters )
    (
      (declare (temporary ) vec4 vec_ctor@0x8580058)
      (assign (constant bool (1)) (x) (var_ref vec_ctor@0x8580058)  (constant vec4 (0.000000 0.000000 0.000000 1.000000)) )
      (assign (constant bool (1)) (y) (var_ref vec_ctor@0x8580058)  (swiz xxxx (var_ref g@0x8580218) ))
      (assign (constant bool (1)) (z) (var_ref vec_ctor@0x8580058)  (constant vec4 (0.000000 0.000000 0.000000 1.000000)) )
      (assign (constant bool (1)) (w) (var_ref vec_ctor@0x8580058)  (constant vec4 (0.000000 0.000000 0.000000 1.000000)) )
      (assign (constant bool (1)) (xyzw) (var_ref gl_FragColor@0x84d32a0)  (var_ref vec_ctor@0x8580058) )
    ))
)

A similar optimization could be done for matrix constructors, but it
is a little more complicate there.

Fixes glsl-uniform-linking-1 and failure to link a shader in Unigine.
An alternative here would be to just ditch using _mesa_add_parameter
and build the initial params list on our own, but that would require
two walks of the list as well.

Bug #29822

cond_update wasn't being set by emit_op3, leading to valgrind
complaints, and failures in several piglit tests when built with
clang.

Previously, using bit-wise operators in some larger expression would
crash on a NULL pointer dereference.  This code at least doesn't crash.

Fixes piglit test bitwise-01.frag.

EGL_MESA_drm_{display,image} can achieve the same functionality.

For some reason r600c, emits extra instructions in the FP to do the depth write output swizzle,
I'm not sure this is required, so here I'm doing it in the exports.

this fixes the mesa trivial demos tri-depthwrite and tri-depthwrite2, it doesn't fix
the glsl1 gl_FragDepth writing test however.

this fixes a few if the fs shader tests, 10 more piglits

sqrt(x) = 1/rsq(x) = x*rsq(x)

This optimization already was in the old GLSL compiler.

Acked on irc by Eric Anholt.

Fixes piglit test glsl-override-builtin.  The linker incorrectly found
the prototype for the float signature, rather than adding a new
prototype with the int return type.  This caused ir_calls with type int
to have their callees set to the float signature, triggering an assert.

this is a bit of a workaround, something is wrong with the literal emits here
so we just use the trig copy function to copy the immd to a temp at start of op.

fix VP/FP LIT tests

This includes several corrections for fixing depth test on sandybridge.
Fix wrong bits definition in depth stencil state. Fix wrong order of
state buffer offset in 3DSTATE_CC_STATE_POINTERS command. Correctly use
buffer width parameter in depth buffer setting.

So as the trig functions used up the literal spots for the PI work, if the arg0 was an immediate
we'd hit failure, so copy the literal before starting.

add some tracking of max temp used to avoid trashing temp regs.

5 more piglits, fp1 COS,SCS,SIN tests

constant splitting was broken for multi-constant cases, fixes fp1 CMP+MAD, vp1 CMP.

Also add an error if we hit this problem again, we need to do this better
possibly tying the literal addition to the last flag.

When releasing the builtin functions, we were just freeing the memory,
not telling the builtin function loader that we had freed its memory.
I wish I had done ARB_ES2_compatibility so we had regression testing
of this path.  Fixes segfault on changing video options in nexuiz.

All pragmas are currently ignored.  Also, the error messages when a
pragma is used incorrectly (i.e., '#pragma debug(on)' inside a
function) are crap, but I think this is sufficient for now.

Fixes piglit test cases pragma-0[1-8].(vert|frag).

Previously, if an attribute was enabled by either a specific GL version
or an extension, the check would require -both- to be enabled.  This bug
was not discovered earlier because version checks are currently only ever
used on their own.

Idea is to build hw state at pipe state creation and
reuse them while keeping a non PM4 packet interface
btw winsys & pipe driver. This commit also force rebuild
of pm4 packet on each call to radeon_state_pm4 which
in turn slow down everythings, this will be addressed.
