Hi!
Please find attached the patch updating NEG_POOL_RANGE from 1008 to
1020 -(8 + <data size>).
Tested with check-gcc with no regression.
The test-case failing for patch 'STRD generation instead of PUSH in A15
ARM prologue' (http://gcc.gnu.org/ml/gcc-patches/2011-11/msg01158.html)
passes with this fix.
gcc/ChangeLog entry:
2011-11-17 Sameera Deshpande <sameera.deshpa...@arm.com>
* config/arm/arm.md (arm_movdi): Update NEG_POOL_RANGE.
(movdf_soft_insn): Likewise.
* config/arm/fpa.md (thumb2_movdf_fpa): Likewise.
* config/arm/neon.md (neon_mov<mode>): Likewise.
* config/arm/vfp.md (movdi_vfp): Likewise.
(movdi_vfp_cortexa8): Likewise.
(movdf_vfp): Likewise.
- Thanks and regards,
