Bug ID: 90854
Summary: Gcc fails to compile a code sample for some parameters
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: zhonghao at pku dot org.cn
Target Milestone: ---
My gcc is 10.0.0, and the code is:
class A
{
int m_fn1 (void *);
int m_fn2 (bool);
};
inline int
A::m_fn2 (bool)
{
static __attribute__ ((section (""))) int a;
if (a)
;
return 0;
}
int
A::m_fn1 (void *)
{
return m_fn2 (0);
}
gcc accepts the code, with some parameters: gcc -Os | gcc -O3 | gcc -O1 | gcc
-Asystem=posix | gcc -Wstrict-prototypes
Meanwhile, it rejects it with others parameters: g++ -O0 | g++ -Dlinux | g++
-Wwrite-strings | g++ -Amachine=i386 | g++ -Wpointer-arith
The error message is strange:
/tmp/ccIBuqiz.s: Assembler messages:
/tmp/ccIBuqiz.s:4: Error: missing name
