| * This patch reworks how llvm targets set Jack Carter2013-01-301-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and update ELF header e_flags. Currently gathering information such as symbol, section and data is done by collecting it in an MCAssembler object. From MCAssembler and MCAsmLayout objects ELFObjectWriter::WriteObject() forms and streams out the ELF object file. This patch just adds a few members to the MCAssember class to store and access the e_flag settings. It allows for runtime additions to the e_flag by assembler directives. The standalone assembler can get to MCAssembler from getParser().getStreamer().getAssembler(). This patch is the generic infrastructure and will be followed by patches for ARM and Mips for their target specific use.

| * Optimize the memory usage of MC bundling, by creating a new type of fragmentEli Bendersky2013-01-151-16/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | into which we can emit single instructions without fixups (which is most instructions). This is an optimization required because MCDataFragment is prety large (240 bytes on x64), with no change in functionality. For large programs, this reduces memory usage overhead required for bundling by 40%. To make the code as palatable as possible, the MCEncodedFragment interface was further fragmented (no pun intended) and MCEncodedFragmentWithFixups is used as the interface to work against when the user expects fixups. MCDataFragment and MCRelaxableFragment implement this interface, while the new MCCompactEncodedInstFragment implements MCEncodeFragment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172572 91177308-0d34-0410-b5e6-96231b3b80d8

So computeFragmentSize can use the generic MCEncodedFragment interface when querying both Data and Relaxable fragments for contents sizes.

| * Make the contents of encoded sections SmallVector<char, N> instead ofEli Bendersky2012-12-071-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | SmallString. This makes it possible to use the length-erased SmallVectorImpl in the interface without imposing buffer size. Thus, the size of MCInstFragment is back down since a preallocated 8-byte contents buffer is enough. It would be generally a good idea to rid all the fragments of SmallString as contents, because a vector just makes more sense. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169644 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | This is more consistent with other vectors in this code. In addition, I ran some tests compiling a large program and >96% of fragments have 4 or less fixups, so SmallVector<4> is a good optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169433 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use a dedicated MachO load command to annotate data-in-code regions. This is the same format the linker produces for final executable images, allowing consistency of representation and use of introspection tools for both object and executable files. Data-in-code regions are annotated via ".data_region"/".end_data_region" directive pairs, with an optional region type. data_region_directive := ".data_region" { region_type } region_type := "jt8" | "jt16" | "jt32" | "jta32" end_data_region_directive := ".end_data_region" The previous handling of ARM-style "$d.*" labels was broken and has been removed. Specifically, it didn't handle ARM vs. Thumb mode when marking the end of the section. rdar://11459456 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157062 91177308-0d34-0410-b5e6-96231b3b80d8
