C--: a portable assembly language that supports garbage collection
(Abstract)
C--: a portable assembly language that supports garbage collection
(Abstract)
For a compiler writer, generating good machine code for a variety of
platforms is hard work. One might try to reuse a retargetable code
generator, but code generators are complex and
difficult to use, and they limit one's choice of implementation
language. One might try to use C as a portable assembly language, but
C limits the compiler writer's flexibility and the performance of the
resulting code. The wide use of C, despite these drawbacks, argues
for a portable assembly language. C-- is a new language designed
expressly for this purpose.
The use of a portable assembly language introduces new problems in
the support of such high-level run-time services as garbage
collection, exception handling, concurrency, profiling, and debugging.
We address these problems by combining the C-- language with a
C-- run-time interface.
The combination is designed to allow the compiler writer a choice of
source-language semantics and implementation techniques, while still
providing good performance.
