Hi Dimitar,
> I'm trying to understand why "read" is not present in link_info.hash.
Simply put it is because newlib (for ARM) does not provide the read() function.
Newlib is a C library implementation and there is no read() function in the C
library specification. The function is meant to be provided by a target
specific system library. Newlib does in fact support target specific system
functions, provided by files in the libc/sys/<target>/ directories, but there
is no implementation of read() in libc/sys/arm/.
There is however an implementation of _read() in libc/sys/arm/syscalls.c so if
the test were to be changed to have pr24406-1.c call _read() and then pass
--wrap=_read on the linker command line, it should work.
But handling this in the test harness seems laborious to me. At least if it is
only for newlib supported ARM environments. But if you want to have a go,
please feel to write a patch and submit it here. I will be happy to review it.
Cheers
Nick
