The C library used throughout this documentation is newlib; however, libgloss could easily be made to support other C libraries. Because libgloss resides in its own tree, it’s able to run standalone, allowing it to support GDB’s remote debugging and to be included in other GNUtools. Several functions that are essential to gcc reside in libgloss. These include the following functions. crt0, the main startup script ld, the linker script I/O support code Top|Contents|Index|Previous|Next   <
