Lightweight tracing helpers for the LLVM Python backend.
|
||
|
|
|
||
|
|
Environment flags (string '1' to enable):
|
||
|
|
- NYASH_CLI_VERBOSE: general lowering/debug logs
|
||
|
|
- NYASH_LLVM_TRACE_PHI: PHI resolution/snapshot wiring logs
|
||
|
|
- NYASH_LLVM_TRACE_VALUES: value resolution logs
|
||
|
|
|
||
|
|
Import and use:
|
||
|
|
from trace import debug, phi, values
|
||
|

|
|
phi("phi message")
