gccint: Host Config

1 19 Host Configuration
1 *********************
1 
1 Most details about the machine and system on which the compiler is
1 actually running are detected by the 'configure' script.  Some things
1 are impossible for 'configure' to detect; these are described in two
1 ways, either by macros defined in a file named 'xm-MACHINE.h' or by hook
1 functions in the file specified by the OUT_HOST_HOOK_OBJ variable in
1 'config.gcc'.  (The intention is that very few hosts will need a header
1 file but nearly every fully supported host will need to override some
1 hooks.)
1 
1  If you need to define only a few macros, and they have simple
1 definitions, consider using the 'xm_defines' variable in your
1 'config.gcc' entry instead of creating a host configuration header.
