1.3 Unsupported GCC features

The following GCC options are not currently supported on Palm OS:

-p
-pg
-a
-ax
-fprofile-arcs
-fbranch-probabilities
Probably profiling is unsupported. Certainly the support functions in `libgcc' aren't being included, because they depend on non-existent stdio support.

-ftest-coverage
A similar comment applies to the gcov data file.

-ffunction-sections
This option sets each function's section after function calls are generated. This is too late to be effective because we need to emit special code for cross-section function calls.

-mbitfield
-m68020
-m68881
These and other M68K hardware selection options will cause your programs to fail horribly.

-mrtd
This selects code generation patterns which disagree with the conventions used by the Palm OS API functions, so will fail horribly.

There are also the following caveats:
