4 | Subject: [PATCH] sysdeps/ieee754: prevent maybe-uninitialized errors | ||
5 | |||
6 | * with -O included in BUILD_OPTIMIZATION when DEBUG_BUILD | ||
7 | is used, nativesdk-glibc fails with: | ||
8 | ../sysdeps/ieee754/ldbl-96/e_jnl.c: In function '__ieee754_jnl': | ||
9 | ../sysdeps/ieee754/ldbl-96/e_jnl.c:146:20: error: 'temp' may be used uninitialized in this function [-Werror=maybe-uninitialized] | ||
10 | b = invsqrtpi * temp / sqrtl (x); | ||
11 | ~~~~~~~~~~^~~~~~ | ||
12 | ../sysdeps/ieee754/ldbl-96/e_jnl.c: In function '__ieee754_ynl': | ||
13 | ../sysdeps/ieee754/ldbl-96/e_jnl.c:375:16: error: 'temp' may be used uninitialized in this function [-Werror=maybe-uninitialized] | ||
14 | b = invsqrtpi * temp / sqrtl (x); | ||
15 | ~~~~~~~~~~^~~~~~ | ||
16 | |||
17 | * work around the issue instead of removing -O like we do with | ||
