Commit: Fix spurious relocation truncated to fit errors for 64-bit PE targets.
Wed Mar 26 16:29:00 GMT 2014
I am applying the patch below to fix a problem for 64-bit PE targets
(specifically Cygwin), whereby the linker can issue spurious
complaints about truncated relocations. What is happening is that the
linker is attempting to resolve a 32-bit relocation against a symbol
in a section that is going to be discarded. So the output section's
address is set to 0, but since we are using 64-bit addresses and the
base address can be above 4Gb, we can end up with an invalid 32-bit
The fix is simple - ignore relocations against discarded sections.
Tested without regressions on an x86_64-pc-cygwin toolchain.
