On RHEL5.1, compile the following gcc code. The compiled ELF code doesn't
contain parasection which is defined by pushsection/popsection in the gcc code.
The compiled .o file still contains parasection. But the linked ELF loses the
section. If changing linker to ld V2.18, the issue is still existing.
The issue is likely either the ld issue or the linked libraries issue.
This is a road blocker for some critical Linux kernel new features to
function. Please help root cause and fix the issue.
int foo2(int a)
{
return a*10;
}
int foo (int a, int b)
{
return a+b;
}
main()
{
int x,y;
//asm volatile ("br.call b0=foo;;");
asm volatile ("mov out0=out0;;\t .pushsection .parasections;\t mov
out0=out0;;\t.popsection");
y = foo2(6);
asm volatile ("mov out0=out0;;");
x= foo(5,6);
return x+y;
}
