Shankar Easwaran 9578442fe9 [ELF] Dont generate PHDR when creating dynamic libraries. 
llvm-svn: 201741
 2014-02-19 23:46:13 +00:00
Shankar Easwaran babba413f5 [ELF] Fix alignment for dynamic relocation sections. 
The sections .rela/.rel.(*) have a alignment of 2 in the final image created by
the linker. This needs to be properly set to the right alignment depending on
the architecture(32/64bits).

 2014-02-01 00:26:33 +00:00
Rui Ueyama 9661bcf2e1 [PECOFF] Handle /machine option before handling all the other options. 
The target machine type affects the meaning of other options, in particular
how to mangle symbols. So we want to handle the option first and then parse
all the other options.

Rui Ueyama 14876abb3d [PECOFF] Set the correct PE header field value.

IMAGE_FILE_LARGE_ADDRESS_AWARE bit for PE32+.

Rui Ueyama ebc13c47f2 [PECOFF] Do not emit a section if it's empty. 
The PE32+ loader does not seem to like an executable with an empty section, so
we should not emit a section if it's empty.

Rui Ueyama 7d1bf45047 [PECOFF] Fix PE/COFF optional header size for PE32+.

Simon Atanasyan 2f1d6366e7 [Mips] Emit ELF header for MIPS target. ELF flags set is mostly hardcoded. 
Later we need to improve that solution and build a correct set of flags
