Package: binutils
Version: 2.15-1
Severity: important
A recent upgrade of binutils started causing some of my builds of
gst-plugins fail. gst-plugins is a little bit odd, since it uses
inline assembly that is intended to be portable to OS/X, so it
uses -Wa,-mregnames in CFLAGS. It appears that the new binutils
on powerpc really does not like variables named 'dec' (and probably
others) if -mregnames is used.
I'm not sure if this change was intended or not. If so, this new
inability to assemble the output of gcc should be documented.
Example code:
---
#include <stdio.h>
void *dec;
int main(int argc, char *argv[])
{
dec = stdin;
printf("%p\n", dec);
return 0;
}
---
Compile log of 'gcc -Wa,-mregnames -c it.c':
