+===========================GNAT BUG DETECTED==============================+
| 4.2.0 20060430 (experimental) (powerpc64-suse-linux-gnu) GCC error: |
| in change_address_1, at emit-rtl.c:1784 |
| Error detected at g-os_lib.adb:2603:1 |
Regression hunting is pointing its finger at this change:
* config/rs6000/rs6000.c (rs6000_override_options): Enable
TARGET_NO_FP_IN_TOC for section anchors.
(optimization_options): Enable section anchors for all
non-"Objective" languages.
In fact, -fno-section-anchors lets it compile again.
