softvfp Selects software floating-point library (FPLib) with
pure-endian doubles. This is the default if you do not specify
a
-fpu option.
softfpa Selects software floating-point library with mixed-endian
doubles.
2.3.8 Generating debug information
This section describes options that enable you to specify whether debug tables are
generated for the current compilation and, if they are, specify their format. See Pragmas
on page 3-2 for more information on controlling debug information.
Note
Optimization criteria can limit the debug information generated by the compiler. See
Defining optimization criteria on page 2-24 for more information.
Debug table generation options
The following options specify how debug tables are generated:
-g This option switches on the generation of debug tables for the current
compilation. The compiler produces the same code whether
-g is used or
is not used. The only difference is the existence of debug tables.
Optimization options for debug code are specified by
-O . By default, the
-g option on its own is equivalent to:
-g -dwarf2 -O0 -gt+p
-g+
is a synonym for -g . It is generated by graphical configurers (the
CodeWarrior IDE for example).
-g- This option switches off the generation of debug tables for the current
compilation. This is the default option.
-gtp This option, when used with -g , switches off the generation of debug
table entries for preprocessor macro definitions. This reduces the size of
the debug image.
-gt-p is a synonym for -gtp .
-gt+p This option, when used with -g , enables preprocessor information. This
is the default option, but some debuggers ignore preprocessor entries.
