From 0f702c6e7097c369517f891c172a84e2e439e9f7 Mon Sep 17 00:00:00 2001 From: Harry Liebel Date: Tue, 17 Dec 2013 18:19:04 +0000 Subject: Create local C library implementation (2/2) - This change is split into two separate patches in order to simplify the history as interpreted by 'git'. The split is between the move/rename and addition of new files. - Remove dependency on toolchain C library headers and functions in order to ensure behavioural compatibility between toolchains. - Use FreeBSD as reference for C library implementation. - Do not let GCC use default library include paths. - Remove unused definitions in modified headers and implementations. - Move C library files to 'lib/stdlib' and 'include/stdlib'. - Break std.c functions out into separate files.
