[Bug ld/13621] dangling global hidden symbol in symtab
http://sourceware.org/bugzilla/show_bug.cgi?id=13621 Richard Henderson changed: What|Removed |Added CC||rth at gcc dot gnu.org --- Comment #3 from Richard Henderson 2012-01-27 20:39:23 UTC --- __TMC_END__ isn't placed in the .bss section. You'd have seen that in the object file. Of course that doesn't happen because there is a section attribute. There is something odd happening though. The .tm_clone_table section is zero sized (which makes sense for all programs that don't use TM). The section is layed out in the map file: .tm_clone_table 0x006008a00x0 .tm_clone_table 0x006008a00x0 z.o but the section is not present in the output (presumably due to the size being zero?). But the two symbols that were in the section get arbitrarily moved to .data: [24] .data PROGBITS 00600898 0898 0004 WA 0 0 4 ... 69: 006008a0 0 OBJECT GLOBAL HIDDEN24 __TMC_LIST__ 70: 006008a0 0 OBJECT GLOBAL HIDDEN24 __TMC_END__ (I adjusted the test case so that the start symbol was also global, so that I could see it in all the output files.) My current guess is that there's some "unused section" pruning code that's triggering to remove the section. My guess is that it should avoid doing that if there are symbols present in the section. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils

Version: 2.29
Status: NEW
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: rth at gcc dot gnu.org
Target Milestone: ---
In bfd/elfxx-sparc.c, there are several code sequences that are
adjusted by various relocations. None of them should occur when
we tell the linker not to change them.
In particular, R_SPARC_TLS_IE_LD{,X} should not optimize instructions
to NOP. There is a current gcc bug with respect to emitting this
relocation; it would have been handy to work around the bug by turning
off the linker optimization.

commit dad0c3bfb5e32ff3f2a03830dc189fe207c7ae00

[Arm, 3/3] Add Execution and Data Prediction instructions for AArch32
This patch is part of the patch series to add support for ARMv8.5-A
extensions.
(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/
exploration-tools)
This patch adds the Execution and Data Prediction Restriction
instructions (that is, cfprctx, dvprxtc, cpprctx). These are all
aliases to MCR and are disassembled as such.
This instruction is retrospectively made optional for all versions of
the architecture from ARMv8.0 to ARMv8.4 and is mandatory from
ARMv8.5. Hence adding a new +predres for older versions of the
architecture.
-
The official name of the extension is v8.0-PredInv.
(You can see this used in the xml descriptions for the new insns, eg:
https://developer.arm.com/docs/ddi0595/b/aarch64-system-instructions/cfp-rctx )
