Anish Athalye f2ab0eb644 Clean up linker script 
This patch does the following:

- Add .text.* to the .text section in the output
- Add an assertion that the trampoline does not overflow a page
- Add the .rodata section
- Make .sdata and .sdata.* (which is for small data) be absorbed into
  the .data section, because we don't need to distinguish between them;
  this prevents .sdata from appearing in the output
- Make the analogous change for .srodata and .sbss
- Make all the data sections 16-byte aligned

This patch also updates the .editorconfig for *.ld files.

Anish Athalye f2df0fa547 Fix ulib's memmove to handle overlap when src<dst 2019-10-08 21:24:03 -04:00
Anish Athalye 8509784d80 Add implementations of memcmp and memcpy to ulib 
This is necessary because gcc may generate calls to memcmp, memset,
memcpy, and memmove when compiling with -nostdlib.
