Using both -m32 and -m64 your test case works perfectly fine for me.

davem@firepit:~/src/GIT/GLIBC/build-sparcv9-multiarch$ cat test.c
#include <stdio.h>
int a = 1;
int b = -1;
long double ll = 2.718281828459L;
volatile long double lla;
volatile long double llb;
int main ()
{
  lla += a * ll;
  llb += b * ll;
  printf ("lla=%Lg, llb=%Lg\n", lla, llb);
  return 0;
}
davem@firepit:~/src/GIT/GLIBC/build-sparcv9-multiarch$ gcc -m32 -O2 -o test
test.c
davem@firepit:~/src/GIT/GLIBC/build-sparcv9-multiarch$ ./test
lla=2.71828, llb=-2.71828
davem@firepit:~/src/GIT/GLIBC/build-sparcv9-multiarch$ gcc -m64 -O2 -o test
test.c
davem@firepit:~/src/GIT/GLIBC/build-sparcv9-multiarch$ ./test
lla=2.71828, llb=-2.71828
