Hi, In <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=925129> you reported a problem with the use of the 'jr $25' instruction on MIPS32R6. Thanks for this report.
I've changed the code to use the new opcode (previously written as 'jal $0,$25') always, since this opcode is supported since the earliest MIPS ISAs. https://git.savannah.gnu.org/gitweb/?p=libffcall.git;a=commitdiff;h=5f801d3d01a079c49c1e84b02ab5a153efd5c428 Bruno
