-
-E

-
-C
,
--comments
¶
Include comments in preprocessed output.
-
-CC
,
--comments-in-macros
¶
Include comments from within macros in preprocessed output.
-

-
-H
,
--trace-includes
¶
Show header includes and nesting depth.
-
-P
,
--no-line-commands
¶
Disable linemarker output in -E mode.
-
-U<macro>

-
-Wp,<arg1>,<arg2>...
¶
Pass the comma separated arguments in <argN> to the preprocessor.
-
-Xpreprocessor
<option>
¶ Pass <option> to the preprocessor.
1.3.6.2. Dependency File Generation¶
tiarmclang options that control generation of a dependency file for make-like build systems.
-
-M
,
--dependencies

-
-MD
,
--write-dependencies
¶
Write a dependency file containing user and system headers.

¶
Add missing headers to dependency file.
-
-MJ<arg>
¶
Write a compilation database entry per input.
-
-MM
,
--user-dependencies
¶
Like -MMD, but also implies -E and writes to stdout by default.
-
-MMD
,
--write-user-dependencies
¶
Write a dependency file containing user headers.
-
-MP
¶
Create phony target for each dependency (other than main file).
-
-MQ<arg>
¶
Specify name of main file output to quote in dependency file.
-
-MT<arg>
¶

-
-dD
¶
Print macro definitions in -E mode in addition to normal output.
-
-dI
¶
Print include directives in -E mode in addition to normal output.
-
-dM
