This puts restrictions on the number of 50# caller-save registers that the compiler can target when building this file. 51# This is required because the code is called from a context in entry.S where 52# very few registers have been saved in the exception handler (for speed 53# reasons). 54# The caller save registers that have been saved and which can be used are 55# r2,r3,r4,r5 : argument passing 56# r15, r18 : SP and LINK 57# tr0-4 : allow all caller-save TR's. The compiler seems to be able to make 58# use of them, so it's probably beneficial to performance to save them 59# and have them available for it. 60# 61# The resources not listed below are callee save, i.e. the compiler is free to 62# use any of them and will spill them to the stack itself. 63 64CFLAGS_tlbex_64.o += -ffixed-r7 \ 65 -ffixed-r8 -ffixed-r9 -ffixed-r10 -ffixed-r11 -ffixed-r12 \ 66 -ffixed-r13 -ffixed-r14 -ffixed-r16 -ffixed-r17 -ffixed-r19 \ 67 -ffixed-r20 -ffixed-r21 -ffixed-r22 -ffixed-r23 \ 68 -ffixed-r24 -ffixed-r25 -ffixed-r26 -ffixed-r27 \ 69 -ffixed-r36 -ffixed-r37 -ffixed-r38 -ffixed-r39 -ffixed-r40 \ 70 -ffixed-r41 -ffixed-r42 -ffixed-r43 \ 71 -ffixed-r60 -ffixed-r61 -ffixed-r62 \ 72 -fomit-frame-pointer 73 74ccflags-y := -Werror 75
