In order for the symbol table in the ELF file to contain the size of functions written in assembly, it is necessary to report it to the assembler using the .size directive. To fulfil the above requirements, this patch introduces an 'endfunc' macro which contains the .endfunc and .size directives. It also adds a .func directive to the 'func' assembler macro. The .func/.endfunc have been used so the assembler can fail if endfunc is omitted. Fixes ARM-Software/tf-issues#295 Change-Id: If8cb331b03d7f38fe7e3694d4de26f1075b278fc Signed-off-by: Kévin Petit <kevin.petit@arm.com>
