I just built an ARM compiler and tried it out on my testcase. It
generated this code for one of the thunks:
.section .text._ZThn8_N1CD1Ev,"ax",%progbits
.align 2
.global _ZThn8_N1CD1Ev
.type _ZThn8_N1CD1Ev, %function
_ZThn8_N1CD1Ev:
.fnstart
@ thunk.cc:25
.LM21:
sub r0, r0, #8
b .LTHUNK0
.fnend
.size _ZThn8_N1CD1Ev, .-_ZThn8_N1CD1Ev
and further down, in the .debug_line section, this:
.byte 0 @ set address *.LM21
.uleb128 0x5
.byte 0x2
.4byte .LM21
.byte 0x2f @ line 25
Same for the other thunk. I think that's all good.
Do you still have concerns about the patch?
