Dear Mr. Northover, Thank you for the quick reply. You are correct about the address-mode operands :) . I guess an important detail left out was that the basic block (call it A) that wants to calculate the address of the target stationary trampoline basic block (call it B) will be moved around in memory during run-time. Our earlier solution, before the feature was implemented to move around (A)

...fined temporary symbol However when only compiling (incompletely via -S), e.g. $clang calc_pi.c -o calc_pi -S , it does compile with the expected outputs and the basic block labels properly generated in my section. I get a file with proper labels e.g. __custom_section: .long 19 .quad .LBB0_0 .long 1 .quad .LBB0_1 .long 28 .quad .LBB0_2 .long 3 ... etc. TLDR: compiles correctly, will not link successfully to make a binary because the symbol of the basic block in the .text section doesn't exist. How do I ensure the Basic Block Symbol does not get destro...

Thx, cheers
