2015-08-04ld: map option for run_dump_test requires no program.Andrew Burgess2-0/+10
When using run_dump_test with the map option to compare the linker map file produced, no additional dump program should be required. A dump program can still be given if needed, but leaving it off will no longer produce an error. ld/testsuite/ChangeLog: * ld/ld-lib.exp (run_dump_test): When using the map option, no program is required.
2015-08-04ld: Add file based error/warning regexp for run_dump_test.Andrew Burgess2-17/+78
The run_dump_test mechanism supports options error and warning, which allow regexp to be specified within the test file, these regexp are matched against the stderr output from the linker. Similar dump test style functions for gas and gdb also support file based matching versions of these options; the patterns are placed into a file which the test driver then references. It is sometimes clearer, when the pattern to be matched spans multiple lines if the patterns can be placed into a separate file. This patch adds new options error_output and warning_output for the linker run_dump_test function. These new options take a filename parameter, this file is then used (with regexp_diff) to compare against the linker output. ld/testsuite/ChangeLog: * ld/ld-lib.exp (run_dump_test): Add error_output and warning_output options.
2015-08-04ld: Add '--require-defined' command line option.Andrew Burgess15-0/+209
Add a new command line option '--require-defined' to the linker. This option operates identically to the '--undefined' option, except that if the symbol is not defined in the final output file then the linker will exit with an error. When making use of --gc-section, or just when trying to pull in parts of a library, it is not uncommon for a user to use the '--undefined' command line option to specify a symbol that the user then expects to be defined by one of the object files supplied to the link. However, if for any reason the symbol is not satisfied by an object provided to the link the user will be left with an undefined symbol in the output file, instead of a defined symbol. In some cases the above behaviour is what the user wants, in other cases though we can do better. The '--require-defined' option tries to fill this gap. The symbol passed to the '--require-defined' option is treated exactly as if the symbol was passed to '--undefined', however, before the linker exits a check is made that all symbols passed to '--require-defined' are actually defined, if any are not then the link will fail with an error. ld/ChangeLog: * ld.texinfo (Options): Document --require-defined option. * ldlang.c (struct require_defined_symbol): New structure.

2015-08-03ld/doc: Document that multiple MEMORY commands are allowed.Andrew Burgess2-3/+9

Update the documentation to make this clear to the users. ld/ChangeLog: * ld.texinfo (MEMORY): Explain that multiple MEMORY commands are acceptable.

2015-07-28Fallout from "Reorder more powerpc64 sections for -z relro"Alan Modra2-9/+13
Commit 23283c1b changed the layout of some bss style sections on powerpc64, but neglected to add a page gap before the third PT_LOAD segment created by this reording. Without a page gap we get two PT_LOAD headers that overlap by one page in memory.
