The purpose of this branch is to switch to using an object file for each
independent function, in order to make linking simpler - instead of
relying on `-ffunction-sections` and `--gc-sections`, which involves the
linker doing the work of linking everything and then undoing work via
garbage collection, this will allow the linker to only include the
compilation units that are depended on in the first place.
This commit makes progress towards that goal.
When exporting math functions for Windows, we provide weak exports of
'l' variants rather than weak aliases. We still use aliases on other
operating systems so that the 'l' variants have one less jump
instruction in this case.
stage2: change logic for detecting whether the main package is inside
the std package. Previously it relied on realpath() which is not portable.
This uses resolve() which is how imports already work.
* stage2: fix cleanup bug when creating Module
* flatten lib/std/special/* to lib/*
- this was motivated by making main_pkg_is_inside_std false for
compiler_rt & friends.
* rename "mini libc" to "universal libc"
