Bug ID: 366079
Summary: FPXX Support for MIPS32 Valgrind
Product: valgrind
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: aleksandar.rik...@imgtec.com
Currently, support for MIPS32 FPXX ABI is incomplete. Programs compiled with
options -mfp64 or -mfpxx are not interpreted correctly on Valgrind which is
compiled with -mfpxx.
Reproducible: Always
Steps to Reproduce:
1. Build Valgrind with this configure: ./configure --host=mipsel-linux-gnu
CFLAGS="-march=mips32r2 -mabi=32 -mfpxx -EL"
2. Build FP test sample (eg. none/tests/mips32/round.c), with -mfp64
3. Run through the Valgrind on Linux 4.1+.
Actual Results:
Illegal instruction / incorrect calculations.
Expected Results:
Correctly executed test.
