The attached patch fixes a bug in sh64 ld, and adds a regression testcase to the ld testsuite. The bug is caused by --gc-sections discarding a section referred to by a datalabel-qualified reference. The following shows the symptoms: $ cat dlsection-1.s .mode SHmedia .text .global start .global foo start: .long datalabel foo .section .text2,"ax" foo: .long 23 $ sh64-elf-as --abi=32 -o dlsection-1.o dlsection-1.s $ sh64-elf-ld -mshelf32 --gc-sections dlsection-1.o dlsection-1.o: In function `start': dlsection-1.o(.text+0x0): undefined reference to `foo' $ (The regression test involves adding a couple of files to the ld testsuite. I wasn't sure of the correct way to represent new files in the patch, please let me know if there's a better way to handle them.) Steve. -- Stephen Clarke, Principal Engineer, SuperH Inc.
