[fpc-devel] Compiling for libgdb, and using make -j on larger SPARC systems
I'm having one of my periodic attempts to check FPC trunk on various architectures, this was going to be a question about an exception when trying to link libgdb into 2.6.2 but I find the behaviour has changed so I mention that for information only. Also for information only, when I used -j 8 for 2.6.2 there was a message about left-over directories, I similarly don't get that with trunk (or it's intermittent) so let's leave it. So the current situation is this: when building FPC trunk on Debian Linux on SPARC, everything is fine if I use NOGDB=1. However, if I try to use libgdb (which has in the past but not particularly recently worked OK on this system) I get this make GDB_V603=1 OPT='-O- -gl' all .. ./fpmake compile --localunitdir=.. --globalunitdir=../packages --os=linux --cpu=sparc -o -Ur -o -Xs -o -O2 -o -n -o -Fu/usr/local/src/fpc/fpc-trunk/rtl/units/sparc-linux -o -Fu/usr/local/src/fpc/fpc-trunk/packages/paszlib/units/sparc-linux -o -Fu/usr/local/src/fpc/fpc-trunk/packages/fcl-process/units/sparc-linux -o -Fu/usr/local/src/fpc/fpc-trunk/packages/hash/units/sparc-linux -o -Fu/usr/local/src/fpc/fpc-trunk/packages/libtar/units/sparc-linux -o -Fu/usr/local/src/fpc/fpc-trunk/packages/fpmkunit/units/sparc-linux -o -O- -o -gl -o -vt -o -dRELEASE --compiler=/usr/local/src/fpc/fpc-trunk/compiler/ppcsparc -bu Start compiling package ide for target sparc-linux.

Hi Mark, this is one of the problems with fpmake, sometimes we seems to loose the output of the calls to the assembler or the linker :( Could you try to run make inside ide directory and add -Xd option to OPT? Does this solve your problem? I get the same kind of error on i386-linux system because the compiler chooses a system library for libreadline.a instead of the one that is in GDBLIBDIR...

[fpc-devel] Cross-compile compiler itself
Hi all, How can I cross-compile the compiler itself? I tried it by: make clean all CPU_TARGET=arm Then: make all CPU_TARGET=arm PP=ppcrossarm But that one failes, because the first step it does is compiling the rtl for the host platform (x86_64). Which fails when ppcrossarm is used for that... There has to be a way, but how? Joost. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

RE: [fpc-devel] Compiling for libgdb, and using make -j on larger SPARC systems
Hi, I am sorry, but Ihave no access to a sprac machine anymore. But I remember that we already had a problem like this coming from the fact that we declare somewhere an empty record and this lead to troubles... TVectorREgss from fpregs unit might still be empty for sparc. This was fixed in http://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/compiler/ncgld.pas?sortby =dater1=19338r2=19337pathrev=19338 in May 2011... But I was hoping it was fixed in 2.6.2 ... Could you try to recompile trunk compiler and check that that one does not crash. Pierre PS :Test bug is tiny: Try to compile the following, with either 2.6.2 or current trunk binary, type emptyrec = record end; var x, y : emptyrec; begin x:=y; end. -Message d'origine- De : fpc-devel-boun...@lists.freepascal.org [mailto:fpc-devel- boun...@lists.freepascal.org] De la part de Mark Morgan Lloyd Envoyé : jeudi 8 août 2013 22:22 À : fpc-devel@lists.freepascal.org Objet : Re: [fpc-devel] Compiling for libgdb, and using make -j on larger SPARC systems Sven Barth wrote: If I revert to 2.6.2 and run ppcsparc under gdb, I get this as a backtrace: Program received signal SIGFPE, Arithmetic exception. 0x001e61c0 in TCGASSIGNMENTNODE__PASS_GENERATE_CODE (this=0xf5d6abe0) at ncgld.pas:785 785 if (right.location.reference.offset mod alignmentrequirement0) or (gdb) bt #0 0x001e61c0 in TCGASSIGNMENTNODE__PASS_GENERATE_CODE (this=0xf5d6abe0) at ncgld.pas:785 Also (if I'm doing this right) (gdb) print alignmentrequirement $1 = 0 Any thoughts appreciated.
