Summary: -ffixed-regs option can't work in mips-elf-gcj
compiler
Product: gcc
Version: 4.4.2
Status: UNCONFIRMED
Severity: blocker
Priority: P3
Component: java
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: licheng.1212@gmail.com
I hava build a cross compiler for my embeded platform
Using built-in specs.
Target: mips-elf
Configured with: ../gcc-4.4.2/configure --prefix=/home/lee/gnu_src/dist
--target=mips-elf --with-newlib
--with-headers=../newlib-1.18.0/newlib/libc/include/
--with-ar=/home/lee/gnu_src/dist/bin/mips-elf-ar
--with-as=/home/lee/gnu_src/dist/bin/mips-elf-as
--with-ld=/home/lee/gnu_src/dist/bin/mips-elf-ld
--with-mpfr=/home/lee/gnu_src/dist --with-gmp=/home/lee/gnu_src/dist
--with-ppl=/home/lee/gnu_src/dist --with-cloog=/home/lee/gnu_src/dist
--enable-languages=c,c++,java --disable-multilib --enable-libgcj
--disable-threads --disable-interpreter --disable-libgcj-bc
--enable-reduced-reflection --with-system-zlib
--with-ecj-jar=/usr/share/java/eclipse-ecj.jar --disable-libjava-multilib
--enable-static --disable-getenv-properties --disable-libunwind-exceptions
--enable-sjlj-exceptions --disable-java-awt --disable-dssi --disable-bootstrap
--disable-plugin --disable-shared --without-x --enable-java-gc=boehm
--without-libffi --disable-jvmpi --disable-tls --disable-java-net
--with-gcc-version-trigger=../gcc-4.4.2/gcc/version.c --disable-libstdcxx-pch
and I add the following option for compiler
-G0 -Wall -msoft-float -march=xcpu -mtune=xcpu -Wa,-march=xcpu,-mtune=xcpu
-mips16 -EL -mexplicit-relocs -fweb -frename-registers -mmemcpy -mmips-tfile
-nostartfiles -nostdlib -nodefaultlibs -c -pipe -ffixed-t3 -ffixed-t4
-ffixed-t5 -ffixed-t6 -ffixed-t7 -ffixed-s2 -ffixed-s3 -ffixed-s4 -ffixed-s5
-ffixed-s6 -ffixed-s7 -ffixed-fp -minterlink-mips16
as it shows, i make some -fixed-regs options for my compiler,and it work OK for
C code, but the java code is still use register s2 ~ fp,I don't konw why?
following is some code fragment disassemble from the final elf file
82056f50 <_ZN9java_main4mainEJvv>:
82056f50: 63f2 addiu sp,-112
82056f52 <$LCFI4>:

82056f72: 67fd move a3,sp

how about of the -ffixed-reg option for gcj?
thanks!!

You have to build the java runtime with -ffixed-reg also.

> You have to build the java runtime with -ffixed-reg also.
The runtime and all my project also have those options
export CFLAGS="-G0 -Wall -mabi=32 -msoft-float -mno-abicalls -march=xcpu
-mtune=xcpu -Wa,-march=xcpu,-mtune=xcpu -mips16 -EL -mexplicit-relocs
-falign-functions=16 -falign-jumps=16 -fweb -frename-registers -mmemcpy
-mmips-tfile -nostartfiles -nostdlib -nodefaultlibs -c -pipe -ffixed-t3
-ffixed-t4 -ffixed-t5 -ffixed-t6 -ffixed-t7 -ffixed-s2 -ffixed-s3 -ffixed-s4
-ffixed-s5 -ffixed-s6 -ffixed-s7 -ffixed-fp -minterlink-mips16
-ffunction-sections -fdata-sections -O0 -g"
export GCJFLAGS=${CFLAGS}

See PR43700, which I suspect was fixed by r172616 on trunk.

I guess !global_regs[regno] vs !fixed_regs[regno] matters for compilation units
that are compiled with -ffixed-$N but where there is no global register
variable declaration for $N in scope. Can you construct a C test case which
shows that gcc clobbers a register $N even though the file is compiled with
-ffixed-$N ?
