Bug ID: 93399
Summary: Annotate assembler option failure
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jamesgua at ca dot ibm.com
Target Milestone: ---
With g++ 8.3.1 version
GNU C++14 (GCC) version 8.3.1 20190507 (Red Hat 8.3.1-4) (x86_64-redhat-linux)
compiled by GNU C version 8.3.1 20190507 (Red Hat 8.3.1-4), GMP version
6.1.2, MPFR version 3.1.6-p2, MPC version 1.0.2, isl version isl-0.16.1-GMP
test case to reproduce:
#include <cstdio>
#include <iostream>
#include <cstring>
int main(int argc, char** argv) {
char* substr = strstr(argv[0], "\n");
char* another = strstr(argv[0], "\r\n");
//printf("found sub string len %d\n", strlen(substr));
//std::cout << "found sub string len " << strlen(substr) << "\n" <<
std::endl;
return 0;
}
failing cmd:
g++ -fverbose-asm -dA -g -O3 -c test.cpp
it's working with older version, g++ 4.8.5, or we can bypass failure with cmd:
g++ -fverbose-asm -g -O3 -c test.cpp
