2016-03-31make xtensa_section_rename () take const char *Trevor Saunders1-1/+1
Xtensa uses it in several macros passing it a literal string, so its convenient for the argument type to be const char *. However some of the code in symbols.c seems to assume tc_canonicalize_symbol_name () will return a non const pointer, and some other target's implementations even modify the argument, so it seems best to return a char * which means casting away const on the argument when we return it instead of another string. gas/ChangeLog: 2016-03-31 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-xtensa.c (struct rename_section_struct): Make old_name const. (xtensa_section_rename): Make argument type const char *. * config/tc-xtensa.h (xtensa_section_rename): Adjust.

2015-08-12xtensa: add --auto-litpools optionMax Filippov1-0/+1
Auto-litpools is the automated version of text-section-literals: literal pool candidate frags are planted every N frags and during relaxation they are turned into actual literal pools where literals are moved to become reachable for their first reference by L32R instruction. 2015-08-12 David Weatherford <weath@cadence.com> gas/ * config/tc-xtensa.c (struct litpool_frag, struct litpool_seg): New structures.
