Hello GCC community.
I am looking for help building GCC 4.9.2 (also tried 4.9.4 and 5.4.0) on
IBM AIX Unix 7.1. Each attempt freezes during the run of build/genmddeps.
This appears to be related to two ld warnings:
ld: 0711-768 WARNING: Object build/genmddeps.o, section 1, function .ferror:
The branch at address 0x3cc is not followed by a recognized
no-op
or TOC-reload instruction. The unrecognized instruction is
0x7C691B78.
ld: 0711-768 WARNING: Object build/genmddeps.o, section 1, function .ferror:
The branch at address 0x3cc is not followed by a recognized
no-op
or TOC-reload instruction. The unrecognized instruction is
0x7C691B78.
The compile/link of genmddeps was this:
g++ -g -DIN_GCC -fno-exceptions -fno-rtti -fasynchronous-unwind-tables
-W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wno-format
-Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros
-Wno-overlength-strings -fno-common -DHAVE_CONFIG_H -DGENERATOR_FILE
-static-libstdc++ -static-libgcc -Wl,-bbigtoc -Wl,-bmaxdata:0x40000000 -o
build/genmddeps \
build/genmddeps.o build/read-md.o build/errors.o
../../build-powerpc-ibm-aix7.1.0.0/libiberty/libiberty.a
So you have the link command via the g++ compiler driver here...
If you add the '-v' option into it you and others will see which linker
was used.
So please try this command in the build directory :
g++ -v -g -DIN_GCC -fno-exceptions -fno-rtti -fasynchronous-unwind-tables \
-W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wno-format \
-Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros \
-Wno-overlength-strings -fno-common -DHAVE_CONFIG_H -DGENERATOR_FILE \
-static-libstdc++ -static-libgcc -Wl,-bbigtoc -Wl,-bmaxdata:0x40000000 \
-o build/genmddeps \
build/genmddeps.o build/read-md.o build/errors.o \
../../build-powerpc-ibm-aix7.1.0.0/libiberty/libiberty.a
Is the 'ld' one from the GNU binutils possible nowadays? Maybe it works...
If the GNU binutils could be used then also cross-compiling things for
IBM AIX Unix 7.1
could be tried - others could try get the same $target compiler for
their Linux etc hosts.
These "gen*" things will be built for the $build system and be run in it
to generate stuff
to be compiled for the $host system. They may succeed on a cross host
but not on the
native IBM AIX host.
But I remember also getting the "proprietary" standard C library for IBM
AIX being a problem.
It being copyrighted and not being available for others, only for those
who own the IBM AIX
target system.
