2021-08-18Fix: return value for GCC _write and _read is written/read chars21.08-rc321.08-rc221.08Davide Grohmann
When using ARMClang compiler the functions _sys_write and _sys_read should return the number of unprocessed characters, whilst when using GCC the functions _write and _read should return the number of processed (i.e., written or read) chars. The code was returning the unprocessed characters value in both cases (i.e., 0) making the calling code to exit early with error and stop further processing when using GCC. Hence no subsequent calls to write would be executed causing missing output on the console. For example, string truncation has been seen when printing on stderr. Note that the bug was not really visible when printing to stdout, but it was immediately exposed when using stderr. This was likely due to the fact that libc buffers the stdout output and flushes it only when encountering a new line char (\n), whilst no buffering is done on stderr. Indeed by printing whole buffers the problem was worked around and went unseen. Change-Id: I5a48d6a29441175b2a950716997332a8b9c34e10
