Bug ID: 93772
Summary: ICE in cgraph.c with lto when symbol not defined
Product: gcc
Version: 9.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: daniel.santos at pobox dot com
CC: marxin at gcc dot gnu.org
Target Milestone: ---
I'm getting an ICE when I try to link while a symbol is used but not defined.
Unfortunately, the project is closed source, so this is about as much as I can
give:
from cgraph.c:
bool
cgraph_edge::possibly_call_in_translation_unit_p (void)
{
...
/* Otherwise we need to lookup prevailing symbol (symbol table is not merged,
yet) and see if it is a definition. In fact we may also resolve aliases,
but that is probably not too important. */
symtab_node *node = callee;
for (int n = 10; node->previous_sharing_asm_name && n ; n--)
node = node->previous_sharing_asm_name;
if (node->previous_sharing_asm_name)
node = symtab_node::get_for_asmname (DECL_ASSEMBLER_NAME (callee->decl));
gcc_assert (TREE_PUBLIC (node->decl)); /* <------ line 3825 */
return node->get_availability () >= AVAIL_AVAILABLE;
}
soures built with:
gcc -DHAVE_CONFIG_H <some CPP flags> -O2 -march=native -g3 -flto -ansi -std=c89
-Wall -Wextra -Wno-unused-parameter -Wno-ignored-qualifiers -Werror=implicit
-MT gpio/my_file.o -MD -MP -MF gpio/.deps/my_file.Tpo -c -o gpio/my_file.o
gpio/my_file.c
link command:
g++ -O2 -march=native -g3 -flto -std=gnu++11 -Wall -Wextra
-Wno-unused-parameter -Wno-ignored-qualifiers -flto -O2 -o my_file <object
files> -lrt -lpthread -Wl,-Bstatic -lboost_date_time -lboost_program_options
-lboost_regex -lboost_system -lboost_thread -Wl,-Bdynamic -lftdi -lusb
