Alan Modra cd6ca96f5d [POWER10] __morestack calls from pcrel code ... Compiling gcc/testsuite/gcc.dg/split-*.c and others with -mcpu=power10 and linking with a non-pcrel libgcc results in crashes due to the power10 pcrel code not having r2 set for the generic-morestack.c functions called from __morestack. There is also a problem when non-pcrel code calls a pcrel libgcc. See the patch comments. A similar situation theoretically occurs with ELFv1 multi-toc executables, when __morestack might be located in a different toc group to its caller. This patch makes no attempt to fix that, since the gold linker does not support multi-toc (gold is needed for proper support of -fsplit-stack code) nor does gcc emit __morestack calls that support multi-toc. * config/rs6000/morestack.S (R2_SAVE): Define. (__morestack): Save and restore r2. Set up r2 for called functions.		2021-07-15 15:27:09 +09:30
