Marco Casaroli ebabdd57f3 arch/arm: Keep GCC from making tail calls in an FDPIC module. ... With -mfdpic and -mlong-calls, GCC turns a call to an imported function in tail position into "ldr r3, [r9, #off]; bx r3". The GOT slot holds the address of the function descriptor, so the branch goes to the descriptor in RAM instead of through it, and the core faults. A normal call loads the code address and the data base from the descriptor first. GCC 13.2 and 15.3 both do this. Only an optimized build makes tail calls. The C++ library of apps/testing/fs/xipfs then faults in its constructor, which ends in a call to syslog(), and the test stops at "stage the C++ module". Pass -fno-optimize-sibling-calls with the other FDPIC flags, in the make build and the CMake build.
