5.8.3.1 XC-DSC C Compiler - General

Notes:

Table 5-20. General Options - C
Option	Description	Command Line
Generate debugging info	N/A
Isolate each function in a section	Check to place each function into its own section in the output file. The name of the function determines the section’s name in the output file. Note: When you specify this option, the assembler and linker may create larger object and executable files and will also be slower. Uncheck to place multiple functions in a section.	`-ffunction-sections`
Place data into its own section	Place each data item into its own section in the output file. The name of the data item determines the name of the section. When you specify this option, the assembler and linker may create larger object and executable files and will also be slower.	`-fdata-sections`
Use 64-bit double	Use `long double` instead of `double` type equivalent to float. Mixing this option across modules can have unexpected results if modules share double data either directly through argument passage or indirectly through shared buffer space.	`-fno-short-double`
Disable instruction scheduling	Prevent the compiler from scheduling instructions.	`-fno-schedule-insns` `-fno-schedule-insns2`
Fill upper value for data in flash	Fill upper flash memory with the value specified.	`-mfillupper=value`
Name the text section	Place text (program code) in a section named `name` rather than the default `.text`section.	`-mtext=name`
