Subject: [PATCH] gcc/mingw: Align `.refptr.` to 8-byte boundaries for 64-bit
targets
Windows only requires sections to be aligned on a 4-byte boundary. This used
to work because in binutils the `.rdata` section is over-aligned to a 16-byte
boundary, which will be fixed in the future.
This matches the output of Clang.
Signed-off-by: LIU Hao <lh_mo...@126.com>
gcc/ChangeLog:
* config/mingw/winnt.cc (mingw_pe_file_end): Add `.p2align`.
