Define various symbols conditionally in shared libraries
The values of symbols in shared libraries like _end, _edata, and
__bss_start are generally not that useful outside of the shared
library. This patch defines them conditionally with PROVIDE, since a
shared library might need the local value. An example is glibc ld.so
local access to "_begin", "_etext" and "_end". (ld.so gains access to
the local values by making the references using hidden visibility.
That makes the definitions hidden too.)
We can't use PROVIDE_HIDDEN in the linker scripts because the shared
library might need the value of the symbol in the executable. An
example is freebsd libc dynamic access to "_end".

ELF dynsyms
Many ELF targets arrange to emit a number of section symbols in
.dynsym for use by dynamic relocations. This happens before the
dynamic relocations are output, and the need for those symbols
determined. In most cases they are not needed. A proper analysis of
the need for dynamic section symbols is target specific and tedious,
so this patch just excludes them in the obvious case when no
dynamic relocations are present.
The patch also runs the new pr23161 and pr23162 tests on more targets.

ELF dynsyms
Many ELF targets arrange to emit a number of section symbols in
.dynsym for use by dynamic relocations. This happens before the
dynamic relocations are output, and the need for those symbols
determined. In most cases they are not needed. A proper analysis of
the need for dynamic section symbols is target specific and tedious,
so this patch just excludes them in the obvious case when no
dynamic relocations are present.
The patch also runs the new pr23161 and pr23162 tests on more targets.

Define various symbols conditionally in shared libraries
The values of symbols in shared libraries like _end, _edata, and
__bss_start are generally not that useful outside of the shared
library. This patch defines them conditionally with PROVIDE, since a
shared library might need the local value. An example is glibc ld.so
local access to "_begin", "_etext" and "_end". (ld.so gains access to
the local values by making the references using hidden visibility.
That makes the definitions hidden too.)
We can't use PROVIDE_HIDDEN in the linker scripts because the shared
library might need the value of the symbol in the executable. An
example is freebsd libc dynamic access to "_end".

ELF dynsyms
Many ELF targets arrange to emit a number of section symbols in
.dynsym for use by dynamic relocations. This happens before the
dynamic relocations are output, and the need for those symbols
determined. In most cases they are not needed. A proper analysis of
the need for dynamic section symbols is target specific and tedious,
so this patch just excludes them in the obvious case when no
dynamic relocations are present.
The patch also runs the new pr23161 and pr23162 tests on more targets.

Define various symbols conditionally in shared libraries
The values of symbols in shared libraries like _end, _edata, and
__bss_start are generally not that useful outside of the shared
library. This patch defines them conditionally with PROVIDE, since a
shared library might need the local value. An example is glibc ld.so
local access to "_begin", "_etext" and "_end". (ld.so gains access to
the local values by making the references using hidden visibility.
That makes the definitions hidden too.)
We can't use PROVIDE_HIDDEN in the linker scripts because the shared
library might need the value of the symbol in the executable. An
example is freebsd libc dynamic access to "_end".

ELF dynsyms
Many ELF targets arrange to emit a number of section symbols in
.dynsym for use by dynamic relocations. This happens before the
dynamic relocations are output, and the need for those symbols
determined. In most cases they are not needed. A proper analysis of
the need for dynamic section symbols is target specific and tedious,
so this patch just excludes them in the obvious case when no
dynamic relocations are present.
The patch also runs the new pr23161 and pr23162 tests on more targets.

Define various symbols conditionally in shared libraries
The values of symbols in shared libraries like _end, _edata, and
__bss_start are generally not that useful outside of the shared
library. This patch defines them conditionally with PROVIDE, since a
shared library might need the local value. An example is glibc ld.so
local access to "_begin", "_etext" and "_end". (ld.so gains access to
the local values by making the references using hidden visibility.
That makes the definitions hidden too.)
We can't use PROVIDE_HIDDEN in the linker scripts because the shared
library might need the value of the symbol in the executable. An
example is freebsd libc dynamic access to "_end".

ELF dynsyms
Many ELF targets arrange to emit a number of section symbols in
.dynsym for use by dynamic relocations. This happens before the
dynamic relocations are output, and the need for those symbols
determined. In most cases they are not needed. A proper analysis of
the need for dynamic section symbols is target specific and tedious,
so this patch just excludes them in the obvious case when no
dynamic relocations are present.
The patch also runs the new pr23161 and pr23162 tests on more targets.

Define various symbols conditionally in shared libraries
The values of symbols in shared libraries like _end, _edata, and
__bss_start are generally not that useful outside of the shared
library. This patch defines them conditionally with PROVIDE, since a
shared library might need the local value. An example is glibc ld.so
local access to "_begin", "_etext" and "_end". (ld.so gains access to
the local values by making the references using hidden visibility.
That makes the definitions hidden too.)
We can't use PROVIDE_HIDDEN in the linker scripts because the shared
library might need the value of the symbol in the executable. An
example is freebsd libc dynamic access to "_end".

ELF dynsyms
Many ELF targets arrange to emit a number of section symbols in
.dynsym for use by dynamic relocations. This happens before the
dynamic relocations are output, and the need for those symbols
determined. In most cases they are not needed. A proper analysis of
the need for dynamic section symbols is target specific and tedious,
so this patch just excludes them in the obvious case when no
dynamic relocations are present.
The patch also runs the new pr23161 and pr23162 tests on more targets.

Define various symbols conditionally in shared libraries
The values of symbols in shared libraries like _end, _edata, and
__bss_start are generally not that useful outside of the shared
library. This patch defines them conditionally with PROVIDE, since a
shared library might need the local value. An example is glibc ld.so
local access to "_begin", "_etext" and "_end". (ld.so gains access to
the local values by making the references using hidden visibility.
That makes the definitions hidden too.)
We can't use PROVIDE_HIDDEN in the linker scripts because the shared
library might need the value of the symbol in the executable. An
example is freebsd libc dynamic access to "_end".
