From bb1a773d5b6bf018bf84fdb3fbba01d3ef54e2c9 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 22 May 2020 20:02:02 -0400 Subject: kill unused dump_fpu() instances dump_fpu() is used only on the architectures that support elf and have neither CORE_DUMP_USE_REGSET nor ELF_CORE_COPY_FPREGS defined. Currently that's csky, m68k, microblaze, nds32 and unicore32. The rest of the instances are dead code.
