sibcall.c (skip_copy_to_return_value): Call identify_call_return_value here, and return orig_insn if it returns zero.
* sibcall.c (skip_copy_to_return_value): Call
identify_call_return_value here, and return orig_insn if it
returns zero. Hardret and softret arguments now unnecessary.
(call_ends_block_p): Don't call identify_call_return_value here.
* ggc-common.c (ggc_mark_rtx_children): No need to mark 'S' or
's' slots in RTXen.
* ggc-page.c, ggc-simple.c (ggc_mark_if_gcable): Delete function.
* ggc.h (ggc_mark_if_gcable): Delete prototype.
testsuite:
* g77.dg: New directory.
* g77.dg/20010216-1.f: New test case.
* g77.dg/dg.exp: New driver.
* lib/g77-dg.exp: New driver library.
