4.8.55 --STRICT: Strict ANSI Conformance
The --STRICT option is used to enable strict ANSI C conformance of all special,
non-standard keywords.
The MPLAB XC8 C compiler supports various special keywords (for example the per-
sistent type qualifier). If the --STRICT option is used, these keywords are changed
to include two underscore characters at the beginning of the keyword (for example,
__persistent) so as to strictly conform to the ANSI standard. Thus if you use this
option, you will need to use the qualifier __persistent in your code, not
persistent.
Be warned that use of this option may cause problems with some standard header files
(e.g., <xc.h>) as they contain special keywords.
See Section 4.9 “MPLAB IDE V8 Universal Toolsuite Equivalents” or
Section 4.10 “MPLAB X Universal Toolsuite Equivalents” for use of this option in
MPLAB IDE.
4.8.56 --SUMMARY: Select Memory Summary Output Type
Use this option to select the type of memory summary that is displayed after compila-
tion. By default, or if the mem suboption is selected, a memory summary is shown. This
shows the total memory usage for all memory spaces.
A psect summary may be shown by enabling the psect suboption. This shows individ-
ual psects, after they have been grouped by the linker, and the memory ranges they
cover. Table 4-16 shows what summary types are available. The output printed when
compiling normally corresponds to the mem setting.
See Section 4.9 “MPLAB IDE V8 Universal Toolsuite Equivalents” or
Section 4.10 “MPLAB X Universal Toolsuite Equivalents” for use of this option in
MPLAB IDE.
4.8.57 --TIME: Report Time Taken For Each Phase of Build Process
Adding the --TIME option when building generates a summary which shows how
much time each stage of the build process took to complete.
4.8.58 --VER: Display the Compiler’s Version Information
The --VER option will display what version of the compiler is running and then exit the
compiler.
