| 2020-01-27 | [ARC] Make libgcc compatible with ARC's reduced register set config. | Claudiu Zissulescu | 1 | -16/+11 | |
| ARC processors can work with a reduced register set (i.e. registers r4-r9 and r16-r25 are not available). This option can be enabled passing -mrf16 option to the compiler, or by using -mcpu=em_mini CPU configuration. Using RF16 config requires all the hand-made assembly files used in libgcc to have the corresponding RF16 object attribute set. This patch qualifies the relevant hand-made assembly files to RF16 config, and also adds generic c-functions for the one which are not. libgcc/ xxxx-xx-xx Claudiu Zissulescu <claziss@synopsys.com> * config/arc/crti.S: Add RF16 object attribute. * config/arc/crtn.S: Likewise. * config/arc/crttls.S: Likewise. * config/arc/lib1funcs.S: Likewise. * config/arc/fp-hack.h (ARC_OPTFPE): Define. * config/arc/lib2funcs.c: New file. * config/arc/t-arc: Add lib2funcs to LIB2ADD. | |||||
