xtensa: allow dynamic configuration
Import include/xtensa-dynconfig.h that defines XCHAL_* macros as fields of a structure returned from the xtensa_get_config_v<x> function call. Define that structure and fill it with default parameter values specified in the include/xtensa-config.h. Define reusable function xtensa_load_config that tries to load configuration and return an address of an exported object from it. Define functions xtensa_get_config_v{1,2} that use xtensa_load_config to get structures xtensa_config_v{1,2}, either dynamically configured or the default. bfd/ * Makefile.am (BFD32_BACKENDS, BFD32_BACKENDS_CFILES): Append xtensa-dynconfig.c. * Makefile.in: Regenerate. * configure: Regenerate. * configure.ac (xtensa_elf32_be_vec, xtensa_elf32_le_vec): Add xtensa-dynconfig.lo to the tb. * elf32-xtensa.c (xtensa-config.h): Replace #include with xtensa-dynconfig.h. (XSHAL_ABI, XTHAL_ABI_WINDOWED, XTHAL_ABI_CALL0): Remove definitions. * xtensa-dynconfig.c: New file. * xtensa-isa.c (xtensa-dynconfig.h): New #include. (xtensa_get_modules): New function. (xtensa_isa_init): Call xtensa_get_modules instead of taking address of global xtensa_modules. gas/ * config/tc-xtensa.c (xtensa-config.h): Replace #include with xtensa-dynconfig.h. (XTHAL_ABI_WINDOWED, XTHAL_ABI_CALL0, XTENSA_MARCH_EARLIEST): Remove definitions. * config/tc-xtensa.h (xtensa-config.h): Replace #include with xtensa-dynconfig.h. * config/xtensa-relax.c (xtensa-config.h): Replace #include with xtensa-dynconfig.h. (XCHAL_HAVE_WIDE_BRANCHES): Remove definition. include/ * xtensa-dynconfig.h: New file. ld/ * emultempl/xtensaelf.em (xtensa-config.h): Replace #include with xtensa-dynconfig.h. (XTHAL_ABI_WINDOWED, XTHAL_ABI_CALL0): Remove definitions.
