powerpc: Fix lgammal_r overflow warnings
|
|
|
c6d234 |
|
|
|
c6d234 |
ldbl-128ibm uses ldbl-128 e_lgammal_r implementation as is, however some
|
|
|
c6d234 |
constants definitions overflows for IBM long double range. This patch
|
|
|
c6d234 |
suppress the compiler warnings until the ldbl-128ibm implementation is
|
|
|
c6d234 |
fixed.
