Bug ID: 68408
Summary: sparc-elf, c++: broken support for attribute
init_priority.
Product: gcc
Version: 5.2.1
Status: UNCONFIRMED
Severity: normal
Hi,
I have been trying to build sparc elf executables from i386. I got
gcc,binutils and newlibc and configured them with target=sparc-elf .
Now when i got gcc and binutils working , i wrote a small program
test.c:
int main()
{
return 3;
}
i compiled it using sparc-elf-gcc -c test.c.
./sparc-elf

On what kind of sparc machine? It sounds like you tried to run the code
on a sparc-solaris or sparc-linux machine, which won't work. sparc-elf
code can only be run on bare hardware.
Try building a cross

The C++ pragma init_priority is enabled for several sparc targets, but not for
the generic sparc-elf (--target=sparc-elf).
Confirmed, a fallout of the illegitimate dependency on the Solaris config

It not fixed on 3.4 or the 4.0 as far as I can see.

What do you mean by as far as I can see? Did you really try with 4.0.0pre?

It is not fixed. In gcc-4.0.0, the file that needs to be fixed is
gcc/config/sparc/sp-elf.h . It should contain the following:
#undef

That's wrong. It is fixed in 4.0.0pre:
gcc -E -DIN_GCC -DCROSS_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes -fno-common -DHAVE_CONFIG_H-I. -Icp
The C++ pragma init_priority is enabled for several sparc targets, but not for
the generic sparc-elf (--target=sparc-elf). The file gcc/config/sparc/elf.h
should include the following lines:
#undef CTORS_SECTION_ASM_OP
#undef DTORS_SECTION_ASM_OP
#define SUPPORTS_INIT_PRIORITY 1
