[Bug binutils/25355] nm reports data variable as "T" with -flto
https://sourceware.org/bugzilla/show_bug.cgi?id=25355
--- Comment #15 from Martin Liška ---
Thank you H.J. I can confirm the patch works:
Before:
$ cat x.c
int nm_test_var;
int nm_test_var2 = 1234;
extern int foo (void);
int
main ()
{
return foo ();
}
$ gcc-9 -fno-common x.c -c -flto && nm x.o
U foo
T main
T nm_test_var
T nm_test_var2
After:
$ ~/bin/binutils/bin/nm --plugin
/usr/bin/../bin/../lib/bfd-plugins/liblto_plugin.so.0.0.0 x.o
U foo
T main
B nm_test_var
D nm_test_var2

[Bug ld/25527] New: [RISC-V] -static-pie not producing relocations
https://sourceware.org/bugzilla/show_bug.cgi?id=25527
Bug ID: 25527
Summary: [RISC-V] -static-pie not producing relocations
Product: binutils
Version: 2.32
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: xerpi.g.12 at gmail dot com
Target Milestone: ---
Trying to compile with -static-pie for a bare-metal target: no dynamic linker
and therefore the relocations have to be resolved by the ELF loader when it
establishes a load address or the executable itself at init by iterating over
the relocatable sections.
The problem is that after linking, the output ELF doesn't contain relocations.
Also attached the output when compiling for aarch64.
$ cat simple.c
typedef void (*fptr)(void);
void func1(void) {}
void func2(void) {}
const fptr table[] = {
func1,
func2,
};
int _start(int i)
{
table[i]();
}
$ cat linker.ld
ENTRY(_start)

[Bug ld/25527] [RISC-V] -static-pie not producing relocations
https://sourceware.org/bugzilla/show_bug.cgi?id=25527 Jim Wilson changed: What|Removed |Added Status|UNCONFIRMED |NEW Last reconfirmed||2020-02-11 CC||wilson at gcc dot gnu.org Ever confirmed|0 |1 --- Comment #1 from Jim Wilson --- I see two problems here. The first problem is that the RISC-V GCC port isn't handling the --static-pie option. For targets that support it, --static-pie should be translated to the linker options "--static --pie --no-dynamic-linker -z text". This doesn't happen for RISC-V as the gcc support is missing. The second problem is that if I manually specify the missing linker options then I get a linker error "-pie is not supported". We do not have support for shared libraries in our embedded toolchain because no one has done a RISC-V shared library port of newlib yet. I get binutils testsuite errors if I enable shared library support, which makes it harder to spot testsuite regressions. Also, I used to get bug reports from users asking why the shared library support was broken because they couldn't get it working. It isn't broken, it is because the newlib support is missing. If I use a linux toolchain, and manually specify the missing linker options, then it works correctly. But the linux toolchain isn't designed for bare metal targets so that probably isn't usable as a workaround. The GCC bug should be fixed and looks easy enough. You could hack around the binutils problem by reverting the patch that disabled shared library support in the embedded elf toolchain. Or maybe I should consider re-enabling the support and find some other way to handle the newlib and testsuite problems. You don't need shared libraries to make static pie work. And the boot loader folks would also like to be able to use static pie or something similar. -- You are receiving this mail because: You are on the CC list for the bug.
[Bug binutils/25355] nm reports data variable as "T" with -flto

Lu : https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=0aa99dcd70bce68f8efef310350a6294e1143382 commit 0aa99dcd70bce68f8efef310350a6294e1143382 Author: H.J. Lu Date: Mon Feb 10 19:01:42 2020 -0800 Use GCC LTO wrapper to get real symbols from LTO IR objects GCC LTO wrapper is needed to extract real symbols from LTO IR objects. This patch does the following: 1. Set up GCC LTO wrapper for each LTO IR object. 2. Run GCC LTO wrapper to get the real object. 3. Extract symbol info from the real object. 4.
