| Enabling | Checks for this warning class are disabled by default,
and require the unnormalized
C ASTs for the project. To enable them, add the following
WARNING_FILTER rule and RETAIN_UNNORMALIZED_C_AST specification to the project configuration file.
Note that retaining the unnormalized ASTs will
increase the disk space used to store the project representation, and
may make the analysis take longer. They also require front end option --cs_ext_pragma_asm_endasm.
RETAIN_UNNORMALIZED_C_AST = Yes EDG_FRONTEND_OPTIONS_PREPEND += --cs_ext_pragma_asm_endasm WARNING_FILTER += allow class="Assembly Pragma" |
