2015-01-20ld: Don't evaluate unneeded PROVIDE expressions.Andrew Burgess11-2/+95
When creating a linker mapfile (using -Map=MAPFILE), we previously would always try to evaluate the expression from a PROVIDE statement. However, this is not always safe, consider: PROVIDE (foo = 0x10); PROVIDE (bar = foo); In this example, if neither 'foo' or 'bar' is needed, then while generating the linker mapfile evaluating the expression for 'foo' is harmless (just the value 0x10). However, evaluating the expression for 'bar' requires the symbol 'foo', which is undefined. This used to cause a fatal error. This patch changes the behaviour, so that when the destination of the PROVIDE is not defined (that is the PROVIDE is not going to provide anything) the expression is not evaluated, and instead a special string is displayed to indicate that the linker is discarding the PROVIDE statement. This change not only fixes the spurious undefined symbol error, but also means that a user can now tell if a PROVIDE statement has provided anything by inspecting the linker mapfile, something that could not be done before. ld/ChangeLog: * ldlang.c (print_assignment): Only evaluate the expression for a PROVIDE'd assignment when the destination is being defined. Display a special message for PROVIDE'd symbols that are not being provided. ld/testsuite/ChangeLog: * ld-scripts/provide-4.d: New file. * ld-scripts/provide-4-map.d: New file. * ld-scripts/provide-4.t: New file. * ld-scripts/provide-5.d: New file. * ld-scripts/provide-5.s: New file. * ld-scripts/provide-5-map.d: New file. * ld-scripts/provide-5.t: New file. * ld-scripts/provide.exp: Run the provide-4.d and provide-5.d tests.
2015-01-20ld/testing: run_dump_test can now check linker mapfiles.Andrew Burgess4-9/+42
Add a new option 'map' to the ld run_dump_test mechanism. When the 'map' option is given run_dump_test will ensure that there is a -Map=MAPFILE present in the linker command line, adding one if needed. The MAPFILE is then compared with the file passed to the new 'map' option using the regexp_diff function. This should make it slightly easier to write tests that check the linker mapfile output. The only test I found that already compares mapfile content is updated to use the new mechanism. ld/testsuite/ChangeLog: * ld-scripts/overlay-size.d: Add 'map' option. * ld-scripts/overlay-size.exp: Remove manual check of mapfile. * lib/ld-lib.exp (run_dump_test): Add support for new 'map' option, checking linker mapfile output.

This moves .got too, which requires .sdata and .sbss to move with it, because these sections share addressing via the toc pointer and with small-model code must be within a 16-bit signed offset. .plt, .iplt and .branch_lt must also be moved since they are addressed via a 32-bit offset from the toc pointer, and we might have a very large .data section. This change means we may have some bss style sections before the data segment, necessitating another PT_LOAD header. Also, since _edata is defined at the end of the data segment it's possible with an empty .data to have _edata at the end of .plt which looks a little unusual since .plt is a bss style section. That should only happen rarely in real world binaries, but does occur in the ld testsuite. ld/ * emulparams/elf64ppc.sh (BSS_PLT): Don't define. (OTHER_READWRITE_SECTIONS): Move .branch_lt to..

Running lang_common before garbage collection means slightly less work in garbage collection code, since common symbols should no longer appear there.

2015-01-19Fallout from recent bfd_reloc_outofrange changesAlan Modra87-195/+312
Commit ec93045b and cd21f5da introduced a large number of tic4x and tic54x regressions, due to the new checks being wrong for targets with octets_per_byte != 1. To fix that I introduced a new bfd_get_section_limit_octets and performed the check on octets rather than byte adresses, reducing the number of bfd_octets_per_byte calls. bfd_octets_per_byte is rather expensive.. I then wondered why the same bfd_reloc_outofrange check added to bfd_perform_relocation wasn't also added to bfd_install_relocation. The two functions are virtually identical and ought to remain that way. However, adding the same check to bfd_install_relocation resulted in ld-elf "FAIL Link eh-group.o to eh-group" on many ELF targets, including x64_64-linux. The reason being that eh-group.o has NONE relocs at the end of a section, and most targets give NONE relocs a non-zero size. So if we are to keep the new outofrange check it appears that NONE relocs must have a zero size. * bfd-in.h (bfd_get_section_limit_octets): New define, extracted from..

ld-elf/gap test was failing due to the ARM backend attempting to output arch symbols when ld -s (strip all symbols) is in force. This patch stops that happening and tidies the code a little.

2015-01-15[Ada] 'first/'last/'length of array whose bound is a discriminantJoel Brobecker7-2/+143
Consider the following code: type Table is array (Positive range <>) of Integer; type Object (N : Integer) is record Data : Table (1 .. N); end record; My_Object : Object := (N => 3, Data => (3, 5, 8)); Trying to print the range and length of the My_Object.Data array yields: (gdb) print my_object.data'first $1 = 1 (gdb) print my_object.data'last $2 = 0 (gdb) print my_object.data'length $3 = 0 The first one is correct, and that is thanks to the fact that the lower bound is statically known. However, for the upper bound, and consequently the array's length, the values are incorrect. It should be: (gdb) print my_object.data'last $2 = 3 (gdb) print my_object.data'length $3 = 3 What happens here is that ada_array_bound_from_type sees that our array has a parallel "___XA" type, and therefore tries to use it. In particular, it described our array's index type as: [...]___XDLU_1__n, which means lower bound = 1, and upper bound is value of "n". Unfortunately, ada_array_bound_from_type does not have access to the discriminant, and is therefore unable to compute the bound correctly. Fortunately, at this stage, the bound has already been computed a while ago, and therefore doesn't need to be re-computed here. This patch fixes the issue by ignoring that ___XA type if the array is marked as already fixed. This also fixes the same issue with packed arrays. gdb/ChangeLog: * ada-lang.c (ada_array_bound_from_type): Ignore array's parallel ___XA type if the array has already been fixed. gdb/testsuite/ChangeLog: * gdb.ada/var_arr_attrs: New testcase.
