[Mlir-commits] [mlir] Use reportFatalInternalError in DialectConversion (PR #178612)

[llvmlistbot at llvm.org]

https://github.com/sladyn98 created https://github.com/llvm/llvm-project/pull/178612

Migrate from deprecated report_fatal_error to reportFatalInternalError in DialectConversion.cpp. All 6 instances are internal consistency checks in MLIR's dialect conversion system, so reportFatalInternalError is the appropriate replacement.

Part of #138914

Subject: [PATCH] mlir: use reportFatalInternalError in DialectConversion

Migrate from deprecated report_fatal_error to reportFatalInternalError
in DialectConversion.cpp. All 6 instances are internal consistency
checks in MLIR's dialect conversion system, so reportFatalInternalError
is the appropriate replacement.
