A few tests use objcopy to convert to verilog or srec output, then check that output is as expected.

2018-09-14PR ld/21375: MIPS: Fix non-zero run-time value for undefined weaksMaciej W. Rozycki4-3/+22
We have an issue in the MIPS backend, with the handling of undefined hidden and internal weak symbols. References to such symbols are supposed to resolve to 0 according to the ELF gABI[1]: "Unresolved weak symbols have a zero value." and the 64-bit MIPS psABI[2]: "If a symbol with one of these [hidden or internal] attributes has no definition within the executable/DSO being linked, then it must be resolved to allocated space if common, resolved to zero if weak, or an error reported otherwise." however if a GOT relocation is used, then a local GOT entry is created and used to satisfy the reference. Such an entry is then (in DSO and PIE binaries) subject to the usual load-time relocation, which means a non-zero value will be returned if the base address is non-zero. This will defeat the usual run-time sequence like: void a (void) __attribute__ ((visibility ("hidden"), weak)); void x (void) { if (a) a (); } This can be reproduced with this simple code: $ cat libtest.c extern int a __attribute__ ((visibility ("hidden"), weak)); int * x (void) { return &a; } $ cat test.c int *x (void); int main (void) { printf ("a: %p\n", x ()); return 0; } $ gcc -shared -fPIC -o libtest.so libtest.c $ gcc -o test test.c -Wl,-rpath,$(pwd) libtest.so $ ./test a: 0x77184000 $ The usual approach targets take is making all the steps required to assign a GOT entry for the symbol referred, and then leave its contents at zero with no dynamic relocation attached, therefore ensuring that the value does not change at load time. However this is not going to work with the implicitly relocated GOT the MIPS psABI specifies[3]: "The dynamic linker relocates the global offset table by first adding the difference between the base where the shared object is loaded and the value of the dynamic tag DT_MIPS_BASE_ADDRESS to all local global offset table entries." and we cannot therefore use the local GOT part. And we cannot offhand use the global part either, as the symbol would then have to be exported and possibly wrongly preempt symbols in other modules involved in the dynamic load, because as per the ELF gABI[1] we are not allowed to enter a hidden or internal symbol into the dynamic symbol table (and then use its associated GOT entry): "A hidden symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object." and: "An internal symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object." So we have to choose something else. Our choice is further limited by the need for the reference associated with the GOT relocation to stay within the signed 16-bit limit from the GOT pointer base register, while being compliant with the ELF gABI and the MIPS psABI. However as Alan Modra has observed[4] one possibility is to edit (relax) the code such that the GOT reference is removed altogether. Based on these observations then modify MIPS BFD linker backend code to: 1. Interpret code associated with GOT relocations and relax the usual LW or LD instructions into a corresponding immediate load operation that places the value of 0 in the intended register, while leaving the GOT entry allocated and initialized as usually. 2. Leave any other instructions associated with GOT relocations in place and instead redirect the reference to a global GOT entry associated with a special `__gnu_absolute_zero' symbol created for this purpose, whose value is 0, SHN_ABS section marks it absolute, binding is global and export class protected, ensuring that the locally provided value is always used at load time, and that the value is not relocated by the dynamic loader. 3. Adjust any high-part GOT relocation used, typically associated with a LUI instruction, accordingly, so that run-time consistency is maintained, either by resolving to the original entry if the instruction associated with the corresponding low-part GOT relocation has been relaxed to an immediate load (in which case the value loaded with LUI will be overwritten), or by also redirecting the reference to `__gnu_absolute_zero' to complete the GOT access sequence if that symbol has been used. 4. Add a target `elf_backend_hide_symbol' hook, for the three MIPS ABIs, which prevents the `__gnu_absolute_zero' symbol from being forced local, to ensure that the redirection works and the symbol remains global/protected with existing linker scripts unchanged. 5. Observing the issue with handling SHN_ABS symbols in the GNU dynamic loader, covered by glibc PR 19818, set the EI_ABIVERSION field in the ELF file header produced to 4 (ABI_ABSOLUTE) if `__gnu_absolute_zero' symbol has been produced and the target configured indicates the GNU operating system, so that broken versions of the GNU dynamic loader gracefully reject the file in loading rather than going astray. Keep EI_ABIVERSION at the original value for other operating systems or if no `__gnu_absolute_zero' symbol has been made. The name of the special `__gnu_absolute_zero' has no meaning other than how a human reader can interpret it, as it is ignored in dynamic loading in the handling of the scenarios concerned. This is because the symbol resolves locally, and it's only the symbol's attributes that matter so that the associated GOT entry remains unchanged at load time. Therefore the name is somewhat arbitrary, observing however the need to use the name space reserved for the system so that it does not conflict with a possible user symbol, and hence the leading underscore, and also the `gnu' infix to denote a GNU feature. Other implementations wishing to address the problem in a similar way may choose a different name and have the solution still work, possibly with a mixture of modules used in a dynamic having symbols of different names provided, which will however not interact with each other due to the protected export class. The symbol can be referred explicitly, however the name is an internal implementation detail rather than a part of the ABI, and therefore no specific semantics is guaranteed. One limitation of this change is that if `__gnu_absolute_zero' has been already defined, then we do not wipe the old definition and all kinds of odd behavior can result. This is however like with other symbols we internally define, such as `_GLOBAL_OFFSET_TABLE_' or `__rld_map', and therefore left as a possible future enhancement. As an optimization the relaxation of LW and LD instructions to a load of immediate zero is always made, even SVR4 PIC code for code that will end up in a regular (non-PIE) executable, because there is a cache advantage with the avoidance of a load from the GOT, even if it is otherwise guaranteed to remain zero. It does not reliably happen though, due to a symbol exportation issue affecting executables, covered by PR ld/21805. One existing test case needs to be updated, as it triggers relaxation introduced with this change and consequently linker output does not match expectations anymore. As we want to keep the original issue covered with the test case modify it then to use the LWL instruction in place of LW, and adjust the output expected accordingly.

2018-08-27x86: Don't mask out the GNU_PROPERTY_X86_UINT32_VALID bitH.J. Lu8-0/+130
Since only the GNU_PROPERTY_X86_UINT32_VALID bit may be set in data-only relocatable objects which don't contain any instructions, linker shouldn't mask out the GNU_PROPERTY_X86_UINT32_VALID bit when merging GNU_PROPERTY_X86_XXX bits. Otherwise, linker output doesn't contain GNU_PROPERTY_X86_XXX property with any data-only relocatable inputs.

GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property. A bit is set if it is set in any relocatable inputs and the property is present in all relocatable inputs: #define GNU_PROPERTY_X86_UINT32_OR_AND_LO 0xc0010000 #define GNU_PROPERTY_X86_UINT32_OR_AND_HI 0xc0017fff 4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED and GNU_PROPERTY_X86_FEATURE_2_XXX bits. GNU_PROPERTY_X86_FEATURE_1_AND is unchanged. GNU_PROPERTY_X86_ISA_1_USED and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful.

2018-08-24ehdr_start twiddlesAlan Modra2-12/+21
We force __ehdr_start to defined in before_allocation, then restore the type and a union after dynamic symbols have been allocated. The union contains a number of structs, all starting with a "next" pointer, and various fields depending on the symbol type. The old code restored the entire union, but it isn't necessary to restore the "next" pointer, and in fact it could be wrong if __ehdr_start happened to be last on the list and some symbols were added before restoring. * emultempl/elf32.em (before_allocation): Don't restore __ehdr_start u.*.next pointer.

2018-08-07PowerPC64 EH info for _notoc linkage stubsAlan Modra5-9/+53
This patch generates EH info for the new _notoc linkage stubs, to support unwinding from asynchronous signal handlers. Unwinding through the __tls_get_addr_opt stub was already supported, but that was just a single stub. With multiple stubs the EH opcodes need to be emitted and sized when iterating over stubs, so this is done when emitting and sizing the stub code. Emitting the CIEs and FDEs is done when sizing the stubs, as we did before in order to have the linker generated FDEs indexed in .eh_frame_hdr. I moved the final tweaks to FDEs from ppc64_elf_finish_dynamic_sections to ppc64_elf_build_stubs simply because it's tidier to be done with them at that point. bfd/ * elf64-ppc.c (struct map_stub): Delete tls_get_addr_opt_bctrl.

One complication is that pc-relative offsets to the PLT may need to be 64-bit in large programs, in contrast to the toc-relative addressing used by older PLT linkage stubs where a 32-bit offset is sufficient until the PLT itself exceeds 2G in size. .eh_frame info to cover the _notoc stubs is yet to be implemented. bfd/ * elf64-ppc.c (ADDI_R12_R11, ADDI_R12_R12, LIS_R12), (ADDIS_R12_R11, ORIS_R12_R12_0, ORI_R12_R12_0), (SLDI_R12_R12_32, LDX_R12_R11_R12, ADD_R12_R11_R12): Define.
