The purpose of this document is to make synchronization of sdcc with GCC cpp easier. The following files has sdcpp specific changes:
- support/cpp/libcpp/files.c:
- __BORLANDC__ specific code
- support/cpp/libcpp/init.c:
- ifdefed NLS support (don't include localedir.h)
- deps_add_default_target(): first parameter is pfile instead pfile->deps
- support/cpp/libcpp/internal.h:
- SDCC _asm specific: __asm and __endasm handling
- _cpp_process_line_notes() returns int instead void
- support/cpp/libcpp/lex.c:
- include assert.h
- added global veriable in_asm
- definition of _cpp_process_line_notes() returns int
- added SDCC _asm specific function _sdcpp_skip_asm_block()
- added sdcpp specific function pedantic_lex_number()
- added sdcpp specific function copy_text_chars()
- added SDCC _asm specific function _sdcpp_save_asm ()
- cpp_get_comments() calls copy_text_chars()
- _cpp_lex_direct() calls sdcpp specific function pedantic_lex_number(), SDCC _asm specific __asm __endasm handling
- support/cpp/libcpp/macro.c:
- macro_real_token_count() returns 0 after abort() to make the compiler happy
- create_iso_definition(): sdcpp specific naked hash handling, added "%s" to cpp_error() to make the compiler happy
- support/cpp/libcpp/mkdeps.c:
