pca006132 4132c450a5 firmware: runtime changes for exception 
Ported from:
M-Labs/artiq-zynq#162

This includes new API for exception handling, some refactoring to avoid
code duplication for exception structures, and modified protocols to
send nested exceptions and avoid string allocation.
 2022-01-26 07:16:54 +08:00
pca006132 536b3e0c26 test: added test case for nested exceptions and try 2022-01-26 07:16:54 +08:00
pca006132 ba34700798 coredevice: report nested exceptions 2022-01-26 07:16:54 +08:00
pca006132 6ec003c1c9 compiler: fixed dead code eliminator 
Instead of removing basic blocks with no predecessor, we will now mark
and remove all blocks that are unreachable from the entry block. This
can handle loops that are dead code. This is needed as we will now
generate more complicated code for exception handling which the old dead
code eliminator failed to handle.

pca006132 da4ff44377 compiler: fixed try codegen and allocate exceptions 
Exceptions are now allocated in the runtime when we raise the exception,
and destroyed when we exit the catch block. Nested exception and try
block is now supported, and should behave the same as in CPython.
Exceptions raised in except blocks will now unwind through finally
blocks, matching the behavior in CPython. Reraise will now preserve
backtrace.

Phi block LLVM IR generation is modified to handle landingpads, which
one ARTIQ IR will map to multiple LLVM IR.

pca006132 4644e105b1 compiler: modified exception representation 
Exception name is replaced by exception ID, which requires no
allocation. Other strings in the exception can now be 'host-only'
strings, which is represented by a CSlice with len = usize::MAX and
ptr = key, to avoid the need for allocation when raising exceptions
through RPC.
