I have seen what's been done for the 68HC11 with gcc:
the implementation had to provide virtual 16- and 32-bit
registers in RAM because gcc assumes a register rich
architecture. The code quality is consequently poor.
Of course, this is fine if all you want a free compiler to play
with.

The 68HC11 represents a much more sophisticated processor
than the 8051. Normal mechanisms, like using stack relative
addressing for parameters, are not an option on the 8051.
