The compiler-rt project provides highly tuned implementations of the
|
|
low-level code generator support routines like "__fixunsdfdi" and other
|
|
calls generated when a target doesn't have a short sequence of native
|
|
instructions to implement a core IR operation. It also provides
|
|
implementations of run-time libraries for dynamic testing tools such as
|
|
AddressSanitizer, ThreadSanitizer, MemorySanitizer, and DataFlowSanitizer.
