Prepare for handling pkg state with files. So it requires having the
path defined before declaring targets. In addition, it cleans up the
old git-download target.
After removing the default definitions of lua module tables and table
lengths (see lua_builtin.h) the symbols have been left undefined, which
results in them getting an address of NULL and a crash if there are no
user symbols and the user attempts a "require".
This patch checks the address of the table length variable and fails the
module search function of the table is not set (i.e. it behaves as if the
table was empty.)
The module searchers in the `require` package should return a string
if the module is not found, and not raise an error.
See: https://www.lua.org/manual/5.3/manual.html#pdf-package.searchers
Also make error strings contain newlines and tabs just like the original
ones.
Upstream lua has many instances of discarding cont qualifiers through
explicit casting. This disables the warnigns for the package so that
they don't show up when one enables -Wno-cast-qual globally.
Prevents error:
clang: error: unknown argument: '-fstack-usage'
clang: error: unknown argument: '-fconserve-stack'
The flags are here to print debug information and try to optimize stack but are
not required.
- Remove file related functions from loader.
* All packages must be builtin.
- Remove os.tmpname.
- Interface with TLSF.
- Don't abort() when out of memory.
- download of v5.3.4 of Lua from git
- building using RIOT build system
- patched to remove the need for _times and _link to be
provided to Lua via newlib.
