|
|
* DESCRIPTION
|
|
*
|
|
* all options for gcc start with '-' and are for the most part
|
|
* single options (no parameters as separate argument).
|
|
* There are of course exceptions to this rule, so here is an
|
|
* exhaustive list of options that do take parameters (potentially)
|
|
* as a separate argument:
|
|
*
|
|
* Compiler:
|
|
* -x language
|
|
* -o filename
|
|
* -aux-info filename
|
|
*
|
|
* Preprocessor:
|
|
* -D name
|
|
* -U name
|
|
* -I dir
|
|
* -MF file
|
|
* -MT target
|
|
* -MQ target
|
|
* (all -i.* arg)
|
|
* -include file
|
|
* -imacros file
|
|
* -idirafter dir
|
|
* -iwithprefix dir
|
|
* -iwithprefixbefore dir
|
|
* -isystem dir
|
|
* -A predicate=answer
|
|
*
|
|
* Linking:
|
|
* -l library
|
|
* -Xlinker option
|
|
* -u symbol
|
|
*
|
|
* Misc:
|
|
* -b machine
|
|
* -V version
|
|
* -G num (see NOTES below)
|
|
*
|
|
* NOTES
|
|
* There is -G option for compatibility with System V that
|
|
* takes no parameters. This makes "-G num" parsing ambiguous.
|
|
* This option is synonymous to -shared, and as such we will
|
|
* not support it for now.
|
|
*
|
|
* Special interest options
|
|
*
|
|
* Assembler Option
|
|
* -Wa,option
|
|
*
|
|
* Linker Options
|
|
* object-file-name -llibrary -nostartfiles -nodefaultlibs
|
|
* -nostdlib -s -static -static-libgcc -shared -shared-libgcc
|
|
* -symbolic -Wl,option -Xlinker option -u symbol --image-base
|
|
*
|
|
* Directory Options
|
|
* -Bprefix -Idir -I- -Ldir -specs=file
|
|
*
|
|
* Target Options
|
|
* -b machine -V version
|
|
*
|
|
* Please note that the Target Options are relevant to everything:
|
|
* compiler, linker, assembler, preprocessor.
|
