The regression reported in PR optimization/7154 showed up
starting with this patch:
2002-05-28 Richard Henderson <rth@redhat.com>
* config/i386/i386.c (ix86_save_reg): Examine regs_ever_live,
not current_function_uses_pic_offset_table and
current_function_uses_const_pool; examine
current_function_profile.
(ix86_expand_prologue): Likewise. Add pic_offset_table_rtx as
input to blockage if needed.
(ix86_expand_call): Do not set
current_function_uses_pic_offset_table.
(legitimize_pic_address): Likewise. Set regs_ever_live for
pic_offset_table_rtx when invoked during reload.
* config/i386/i386.h (FINALIZE_PIC): Remove.
* config/i386/i386.md (tablejump): Reformat. Do not set
current_function_uses_pic_offset_table.
(tls_global_dynamic, tls_local_dynamic_base): Likewise.
(blockage): Accept anything as operand 0.
Output from the compiler when compiled with "-c -O -fPIC"
on i686-linux:
7154.c: In function `foo':
7154.c:6: internal compiler error: in verify_initial_elim_offsets,
at reload1.c:3350
