cc97067fa1 Add C++ support to Makefile, and proof-of-concept simple.cpp example
This is a work in progress based on @mikejac's work.

Missing:
* No 'new' operator.
* I don't think STL is currently supported.

a3d7732da8 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.

4c89a0574b Add sanity-test suite to unaligned_load.c

f47aa77982 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.

7ebebf6d22 unaligned_load: Add doubleexceptionvector behaviour test 2015-09-15 12:00:26 +10:00
Angus Gratton
c7a7dfdf82 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.

7e73693898 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')

0090153fa7 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.
