From: "lucier at math dot purdue dot edu" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/13926] New: GCC generates jumps that are too large to fit in word displacement field Date: Fri, 30 Jan 2004 04:07:00 -0000 [thread overview] Message-ID: <20040130040702.13926.lucier@math.purdue.edu> (raw) This is reported against 3.3.1 since that's what I have readily available now, but I believe it also occurs in 3.4 and mainline. With the following file: http://www.math.purdue.edu/~lucier/bugzilla/5/_meroon.i.gz while trying to instrument it using gcov, I get the following error: banach-2% gcc -I/export/mdd0/users/lucier/local/gambit/include -m64 -fPIC -O0 -f no-math-errno -fno-trapping-math -mtune=ultrasparc -c -D___DYNAMIC -D___SINGLE_H OST -D___OPTIMIZE_SPACE -ftest-coverage -fprofile-arcs -save-temps _meroon.c /usr/ccs/bin/as: "_meroon.s", line 450662: error: word displacement will not fit in 19 bits /usr/ccs/bin/as: "_meroon.s", line 35282: error: word displacement will not fit in 19 bits /usr/ccs/bin/as: "_meroon.s", line 35341: error: word displacement will not fit in 19 bits /usr/ccs/bin/as: "_meroon.s", line 35391: error: word displacement will not fit in 19 bits /usr/ccs/bin/as: "_meroon.s", line 35416: error: word displacement will not fit in 19 bits /usr/ccs/bin/as: "_meroon.s", line 35466: error: word displacement will not fit in 19 bits <repeated a few thousand times> Basically, gcc on sparc64 generates predicated jumps over 2MB instead of using an indirect jump. (Perhaps this is the largest function ever occuring in a bugzilla report ;-) Brad -- Summary: GCC generates jumps that are too large to fit in word displacement field Product: gcc Version: 3.3.1 Status: UNCONFIRMED Severity: normal Priority: P2 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: lucier at math dot purdue dot edu CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: sparc-sun-solaris2.8 GCC host triplet: sparc-sun-solaris2.8 GCC target triplet: sparc-sun-solaris2.8 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13926
