The problem here is that x32 is really using 64-bit addressing, while pretending to be 32-bit. Even though the object file format is 32-bit, we need to do the overflow checking with 64-bit arithmetic (because that's what the hardware will be using). This patch overrides the pcrela32_check functions in reloc.h with target-specific versions that do 64-bit checking. I've also updated the test case to use -Tdata instead of adding a huge .space directive, to reduce the size of the .o files. gold/ PR gold/19567 * reloc.h (Relocate_functions::Overflow_check): Add comments. * x86_64.cc (X86_64_relocate_functions): New class. (Target_x86_64::Relocate::relocate): Use the new class. * testsuite/Makefile.am (x86_64_overflow_pc32): Add -Tdata option. (x32_overflow_pc32): New test case. * testsuite/Makefile.in: Regenerate. * testsuite/x32_overflow_pc32.sh: New script. * testsuite/x86_64_overflow_pc32.s: Remove .space directive.
