This puts restrictions on the number of 42# caller-save registers that the compiler can target when building this file. 43# This is required because the code is called from a context in entry.S where 44# very few registers have been saved in the exception handler (for speed 45# reasons). 46# The caller save registers that have been saved and which can be used are 47# r2,r3,r4,r5 : argument passing 48# r15, r18 : SP and LINK 49# tr0-4 : allow all caller-save TR's. The compiler seems to be able to make 50# use of them, so it's probably beneficial to performance to save them 51# and have them available for it. 52# 53# The resources not listed below are callee save, i.e. the compiler is free to 54# use any of them and will spill them to the stack itself. 55 56CFLAGS_fault_64.o += -ffixed-r7 \ 57 -ffixed-r8 -ffixed-r9 -ffixed-r10 -ffixed-r11 -ffixed-r12 \ 58 -ffixed-r13 -ffixed-r14 -ffixed-r16 -ffixed-r17 -ffixed-r19 \ 59 -ffixed-r20 -ffixed-r21 -ffixed-r22 -ffixed-r23 \ 60 -ffixed-r24 -ffixed-r25 -ffixed-r26 -ffixed-r27 \ 61 -ffixed-r36 -ffixed-r37 -ffixed-r38 -ffixed-r39 -ffixed-r40 \ 62 -ffixed-r41 -ffixed-r42 -ffixed-r43 \ 63 -ffixed-r60 -ffixed-r61 -ffixed-r62 \ 64 -fomit-frame-pointer 65 66EXTRA_CFLAGS += -Werror 67
