# 64-bit Safety In the Compiler
|
|
|
|
An issue that has arisen recently for contributors making changes to the GLSL ES
|
|
grammar files has been that certain versions of flex, the lexer on which ANGLE
|
|
relies, produce outputs which are not safe in 64-bit builds.
|
|
|
|
To address this issue, ANGLE has added a step to its generation scripts to apply
|
|
64-bit safety fixes to newly regenerated outputs. This should be unnoticeable to
|
|
developers invoking flex via the generate\_parser.sh scripts in the relevant
|
|
compiler directories, as the fixes will be applied by the patch utility as part
|
|
of that script.
|
|
|
|
When making code contributions that affect the grammar files, please ensure that
|
|
you've generated the outputs using the script, to make certain that the 64-bit
|
|
safety fixes are applied.
