i686-apple-darwin10-gcc-4.2.1 generated the following warning.
warning: 'score' may be used uninitialized in this function
GCC 4.4.3 on Linux didn't generate the above warning.
The 'vec4[12] foo' style already worked, but the 'vec4 foo[12]' style
did not. Also, 'vec4[] foo' was wrongly accepted.
Fixes piglit test cases array-19.vert and array-21.vert.
May fix fd.o bug #29684 (or at least part of it).
The code would attempt to add a new signature to the ir_function, which
didn't exist. Simply bailing out/returning early seems reasonable.
Fixes piglit test redeclaration-02.vert, and fixes a crash in
redeclaration-03.vert (the test still fails).
This should make it easier to diff the output, clean up some of the
insane whitespace, and make the strings a bit smaller.
We'll probably need to split up the prototype strings eventually, but
for now, this gets it under the 65K mark.
Calls to equal(bvec, bvec) or notEqual(bvec, bvec) previously caused an
assertion. Fixes piglit tests glsl-const-builtin-equal-bool and
glsl-const-builtin-notEqual-bool.
Carefully avoiding printing any error when the new definition matches
the existing definition.
This fixes the recently-added 088-redefine-macro-legitimate.c and
089-redefine-macro-error.c tests as well as glsparsertest/preprocess1
in piglit.
The specification says that redefining a macro is an error, unless the
new definitions is identical to the old one, (identical replacement
lists but ignoring differing amounts of whitespace).
In commit 6be3a8b70a, the #version directive
was fixed to stop generating a spurious newline. Here we simply update
the expected result for the single test which includes a #version directive.
Matching the newline here meant having to do some redundant work here,
(incrementing line number, resetting column number, and returning a
NEWLINE token), that could otherwise simply be left to the existing rule
which matches a newline.
Worse, when the comment rule matches the newline as well, the parser
can lookahead and see a token for something that should actually be skipped.
For example, in a case like this:
#if 0 // comment here
fail
#else
win
#endif
Both fail and win appear in the output, (not that the condition is being
evaluated incorrectly---merely that one token after the comment's newline
was being lexed/parse regardless of the condition).
This commit fixes the above test case, (which is also remarkably similar
to 087-if-comments which now passes).
This error led to an assertion failure for some constructors of
non-square matrices. It only occured in matrices where the number of
columns was greater than the number of rows. It didn't even always
occur on those.
Fixes piglit glslparsertest case constructor-16.vert.
When simplifying (vec4(1.0) / (float(x))) to rcp(float(x)), we forgot
to produce a vec4, angering ir_validate when starting alien-arena.
Fixes:
glsl-algebraic-add-zero-2
glsl-algebraic-div-one-2
glsl-algebraic-mul-one-2
glsl-algebraic-sub-zero-3
glsl-algebraic-rcp-sqrt-2
Several optimization paths, including constant folding, can lead to
accessing an ir_constant array with an out of bounds index. The GLSL
spec lets us produce "undefined" results, but it does not let us
crash.
Fixes piglit test case glsl-array-bounds-01 and glsl-array-bounds-03.
