[ELF] - Implemented --section-start, -Ttext, -Tdata, -Tbss options. --section-start=sectionname=org Locate a section in the output file at the absolute address given by org. You may use this option as many times as necessary to locate multiple sections in the command line. org must be a single hexadecimal integer; for compatibility with other linkers, you may omit the leading `0x' usually associated with hexadecimal values. Note: there should be no white space between sectionname, the equals sign (“<=>”), and org. -Tbss=org -Tdata=org -Ttext=org Same as --section-start, with .bss, .data or .text as the sectionname.

[ELF] - Make LLD accept Ttext-segment X/Ttext-segment=X aliases for -Ttext. It os used in work/emulators/qemu-user-static port. Which tries to use -Ttext-segment and then: # In case ld does not support -Ttext-segment, edit the default linker # script via sed to set the .text start addr. This is needed on FreeBSD # at least. <here it calls -verbose to extract and edit default bfd linker script.> Actually now we are do not fully support -Ttext properly (see D27613), but we also seems never will provide anything close to default script, like bfd do, so at least this patch introduces proper alias handling. llvm-svn: 289827

[ELF] - Allow "-Ttext xxx", "-Tbss xxx", "-Tdata bss" commandline. So patch just defines an alias for -Txxx=YYY forms, this is consistent with ld and should fix PR30814. llvm-svn: 285824
