[libc] Implement FLAGS option for generating all combinations for targets. Add FLAGS option for add_header_library, add_object_library, add_entrypoint_object, and add_libc_unittest. In general, a flag is a string provided for supported functions under the multi-valued option FLAGS. It should be one of the following forms: FLAG_NAME FLAG_NAME__NO FLAG_NAME__ONLY A target will inherit all the flags of its upstream dependency. When we create a target TARGET_NAME with a flag using (add_header_library, add_object_library, ...), its behavior will depend on the flag form as follow: - FLAG_NAME: The following 2 targets will be generated: TARGET_NAME that has FLAG_NAME in its FLAGS property. TARGET_NAME.__NO_FLAG_NAME that depends on DEP.__NO_FLAG_NAME if TARGET_NAME depends on DEP and DEP has FLAG_NAME in its FLAGS property. - FLAG_NAME__ONLY: Only generate 1 target TARGET_NAME that has FLAG_NAME in its FLAGS property. - FLAG_NAME__NO: Only generate 1 target TARGET_NAME.__NO_FLAG_NAME that depends on DEP.__NO_FLAG_NAME if DEP is in its DEPENDS list and DEP has FLAG_NAME in its FLAGS property. To show all the targets generated, pass SHOW_INTERMEDIATE_OBJECTS=ON to cmake. To show all the targets' dependency and flags, pass SHOW_INTERMEDIATE_OBJECTS=DEPS to cmake. To completely disable a flag FLAG_NAME expansion, set the variable SKIP_FLAG_EXPANSION_FLAG_NAME=TRUE.

[libc] add sprintf This adds the sprintf entrypoint, as well as unit tests. Currently sprintf only supports %%, %s, and %c, but the other conversions are on the way. Reviewed By: sivachandra, lntue Differential Revision: https://reviews.llvm.org/D125573 | 4 年前 | |
[libc] refactor printf file writing Add return values to converter functions to allow for better error handling when writing files. Also move the file writing code around to be easier to read. Reviewed By: sivachandra Differential Revision: https://reviews.llvm.org/D127773 | 4 年前 |
