9d62d09d3f unaligned_load.c: Added more naive_strcpy tests
Added tests for naive_strcpy using a variety of different regs, as execution time can depend on which register is being used.

dc1b8b1816 Add sanity-test suite to unaligned_load.c
Tests are designed to methodically exercise all code paths/opcodes/offsets/etc.

3eb43c6ef5 Moved DoubleLoadStorageHandler to end of functions, improve fast path l8ui performance
This allows a conditional branch that previously required a full jump instruction not to require it.

5a9590cdff unaligned_load: Add doubleexceptionvector behaviour test 2015-09-15 12:00:26 +10:00

e4c76b488c Remove the unaligned load handler to its own source file as it was getting quite complex
The downside here is needing to use #include so the 'beq' in the
exception vector can land on it directly, save an instruction.

There might be a better way to do this, but it seems hard to "curate"
the order that symbols appear in each section.

1221e2117b Rework component makefiles to have a default <component>_ROOT
This fixes a long-standing bug where build directories sometimes
expanded many levels deeper than they should have.

Component names can now no longer contains slashes (ie the component
name for 'extras/i2c' is now just 'i2c')

c19bb63286 Reorder library arguments so component libraries come first
This allows components to override weak linked symbols in the core or
the SDK libraries, without needing to force symbol discovery.

Will help with #24, for instance.
