| # This is the libgcc host-specific configuration file |
| # where a configuration type is mapped to different system-specific |
| # definitions and files. This is invoked by the autoconf-generated |
| # configure script. Putting it in a separate shell file lets us skip |
| # running autoconf when modifying host-specific information. |
| |
| # This file bears an obvious resemblance to gcc/config.gcc. The cases |
| # should be kept similar, to ease moving library-specific settings |
| # from config.gcc to this file. That is also why tmake_file is |
| # left as tmake_file, rather than hmake_file, even though this library |
| # switches on ${host}. |
| |
| # This file switches on the shell variable ${host}, and also uses the |
| # following shell variables: |
| # |
| # with_* Various variables as set by configure. |
| |
| # This file sets the following shell variables for use by the |
| # autoconf-generated configure script: |
| # |
| # asm_hidden_op The assembler pseudo-op to use for hide |
| # lists for object files implemented in |
| # assembly (with -fvisibility=hidden for C). |
| # The default is ".hidden". |
| # cpu_type The name of the cpu, if different from the first |
| # chunk of the canonical host name. |
| # extra_parts List of extra object files that should be compiled |
| # for this target machine. This may be overridden |
| # by setting EXTRA_PARTS in a tmake_file fragment. |
| # If either is set, EXTRA_PARTS and |
| # EXTRA_MULTILIB_PARTS inherited from the GCC |
| # subdirectory will be ignored. |
| # tmake_file A list of machine-description-specific |
| # makefile-fragments, if different from |
| # "$cpu_type/t-$cpu_type". |
| |
| asm_hidden_op=.hidden |
| extra_parts= |
