Binary package hint: xulrunner-1.9.1
Either this file should be built individually as ARM code using -marm, or the code needs to be reviewed and modified to be Thumb-2 safe.
Specifically, calling a function using:
mov lr, pc
mov pc, ip
...will not interwork properly between ARM and Thumb state, depending on the function called.
Instead, something like the following is needed:
#ifdef __thumb__
adr lr, 0f + 1 /* store return address in lr, setting the Thumb bit [0] */
bx ip
0:
#else
mov lr, pc
mov pc, ip
#endif
I'll try and propose a suitable patch.
I'm currently scanning to see whether there is other problematic code in this package. |

Binary package hint: xulrunner-1.9.1
Two issues:
1) Either this file should be built individually as ARM code using -marm, or the code needs to be reviewed and modified to be Thumb-2 safe.
Specifically, calling a function using:
mov lr, pc
mov pc, ip
...will not interwork properly between ARM and Thumb state, depending on the function called.
Instead, something like the following is needed:
#ifdef __thumb__
blx ip
0:
#else
mov lr, pc
mov pc, ip
#endif
I'll try and propose a suitable patch.
I'm currently scanning to see whether there is other problematic code in this package.
Patch posted below.
2) The kernel user helpers are not currently used for implementing atomic operations. (This is the same backend used by the GCC __sync_*() atomic intrinsics.)
There is a configure option --with-arm-kuser to enable this, but it's not currently bassed by the build rules. It's been supported since ff 3.5 / linux 2.6.17 (if I remember correctly) |
