Re: Nightly test result of systemtap in ppc64
Hi -
Hien sent me the ppc64 C and assembly files for his test case. The
problem is relatively typical for powerpc: TOC overflow. In this
case, the ".toc1" section, used for storing addresses of string
literals and ordinary non-auto variables, runs out of space after 8k
of them.
We know we have plenty of work to do in improving the quality and
reducing the quantity of C code being generated. In the mean time,
adding "-fminimal-toc" to the generated ppc64 Makefile CFLAGS should
solve this problem, at the cost of slower performance.
