74704e80c6 glcpp: Print to the main compiler's infolog, not stdout. 2010-06-21 12:41:05 -07:00

4a2bbdacfc Use yy_scan_string and stop caring about shader->SourceLen. 
We had to call strlen on the preprocessed source, which seemed a bit
pointless; also, we updated shader->SourceLen but not shader->Source,
which was even more confusing.  Just leave both untouched.

26e761edb2 glcpp: Rework handling of "defined" operator. 
It's now done in the grammar, and as a result, can easily handle
parenthesis.  defined ( identifier ) is now supported.

Fixes glcpp/tests/065-if-defined-parens.c.

bac0e371e3 glcpp/tests: Add a test for #if defined (identifier) 
Previously we only tested #if defined identifier (without parenthesis).

6587574354 glcpp: Ignore junk tokens at end of #ifdef/#ifndef (with warning) 
Both nVidia's compiler and GCC accept this.
Fixes CorrectPreprocess11.frag.

62b4b7785a glcpp: Add boolean 'error' flag. 
We used to check if the info log is non-empty, but when we print
warnings, this will no longer be valid.

33eaa3e0b3 glcpp: Rename "errors" to "info_log." 
Eventually, we'll want to be be able to print out warnings as well.

214632f527 glcpp/tests: Add a test for #version followed by #define. 
This isn't really a C file, but...that's probably okay.

8f32221638 glcpp: Fix line and column numbering. 
Lines were off by one, and column numbering was completely daft.

e8e93a4543 glcpp: Remove calls to exit(). 
Calling exit() would be really bad once integrated into mesa.  Even in
the standalone binary, we want to print the error log first.

Since each case already flags an error, compilation will still fail,
but it may go on (with something fudged) and generate more errors.

77260fc0a0 glcpp: Actually support #ifdef and #ifndef. 
Strangely, the lexer never created these tokens, even though the parser
already had code to handle them.

b673ff91ab glcpp: Print errors on stdout instead of stderr (non-standalone version). 
Otherwise, piglit marks tests as "warn" when the shader was (correctly)
failing.

3370c5f90b glcpp/tests: Add extra newline at the end of expected output. 
This newline at EOF is harmless and generated by the previous commit.

3b73ea36c4 glcpp: Pass #version, #extension, and #pragma directives through unchanged. 
Let the main compiler's lexer/parser handle them.

04ba86a536 Make the main compiler call the preprocessor. 
By using a single function, the main compiler doesn't need to include
glcpp.h, which currently has a lot of details about the preprocessor
internals.  In particular, this prevents the two yacc grammars from
seeing each other, which would be rather messy to sort out.

1b1f43e608 glcpp: Add support for lexing from a string. 
The standalone binary still reads from stdin, however.

4c8a1af811 glcpp: Output to a buffer and error log rather than directly printing. 
In the standalone case, simply print the buffers when done.
