Compiler
-xassembler-with-cpp
Function: Invoking C preprocessor
Description: When this option is specified, the
cpp
C preprocessor will be executed before the source is
assembled. This allows assembly sources to include preprocessor instructions (
#define
,
#in-
clude
, etc.).
Default: The C preprocessor is not invoked.
-Wa,
<option>
Function:
Specify an assembler option
Description: The specified option will be passed to the assembler. To specify two or more options, input as
many instances of
-Wa,
<option> as necessary.
Default: No option will be passed to the assembler.
When entering options in the command line, you need to place one or more spaces before and after the option.
Example:
xgcc -c -gstabs test.c
notes : • Be aware that the compile processing will be unsteady if the same compiler option is specified
twice or more with different settings.
• Be sure to specify one of the
-S
,
-E
or
-c
options when invoking
xgcc
. If none are specified,
xgcc
continues processing until the linkage stage. Note, however, that necessary linker
options cannot be specified in this case.
• Generate all the objects to be linked using the same
-mpointer16
and
-mshort-offset
option combination in compiling and assembling. Objects that were generated with different
option specifications may not be linked normally.
Example of compiling:
xgcc -B$(TOOL_DIR)/ -c -O -gstabs -fno-builtin -I$(TOOL_DIR)/in-
clude -mpointer16 -mshort-offset main.c
When the
-c
option is specified, the
-mpointer16
option will also be passed to the
assembler.
Example of assembling:
xgcc -B$(TOOL_DIR)/ -c -xassembler-with-cpp -Wa,--gstabs
-Wa,-mpointer16 boot.s
After
boot.s
is processed in the preprocessor, it will be assembled with the
-mpointer16
option specified.
