Laurent GUERBY <laurent at guerby dot net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ebotcazou at gcc dot | |gnu.org --- Comment #1 from Laurent GUERBY <laurent at guerby dot net> 2010-12-27 22:26:40 UTC --- I took one of the test and it fails to link at -O2 and -O1 but works and PASS at -O0, see below. So I'm assuming some optimization is creating the issue, any idea on what to look for? gue...@babe:~/tmp$ gnatmake -f -O2 c390002.adb gcc -c -O2 c390002.adb c390002.adb:101:11: warning: unreachable code gcc -c -O2 report.adb report.adb:312:30: warning: index for "NAM" may assume lower bound of 1 report.adb:312:30: warning: suggested replacement: "NAM'First + 2" report.adb:312:33: warning: index for "NAM" may assume lower bound of 1 report.adb:312:33: warning: suggested replacement: "NAM'First + 6" gnatbind -x c390002.ali gnatlink c390002.ali -O2 ./c390002.o: In function `_ada_c390002': c390002.adb:(.text+0x1070): undefined reference to `c390002__vehicle___alignment.1865' c390002.adb:(.text+0x1071): undefined reference to `c390002__vehicle__objectDF.1869' c390002.adb:(.text+0x1072): undefined reference to `c390002__vehicle__create.1880' c390002.adb:(.text+0x1082): undefined reference to `c390002__vehicle__wheels.1883' c390002.adb:(.text+0x16d0): undefined reference to `c390002__motivators___alignment.2087' c390002.adb:(.text+0x1cc0): undefined reference to `c390002__motivators___alignment__2.2292' c390002.adb:(.text+0x22a0): undefined reference to `c390002__motivators___alignment__3.2497' collect2: ld returned 1 exit status gnatlink: error when calling /home/guerby/install-trunk/bin/gcc gnatmake: *** link failed. gue...@babe:~/tmp$ gnatmake -f -O1 c390002.adb gcc -c -O1 c390002.adb c390002.adb:101:11: warning: unreachable code gcc -c -O1 report.adb report.adb:312:30: warning: index for "NAM" may assume lower bound of 1 report.adb:312:30: warning: suggested replacement: "NAM'First + 2" report.adb:312:33: warning: index for "NAM" may assume lower bound of 1 report.adb:312:33: warning: suggested replacement: "NAM'First + 6" gnatbind -x c390002.ali gnatlink c390002.ali -O1 ./c390002.o: In function `_ada_c390002': c390002.adb:(.text+0x1041): undefined reference to `c390002__vehicle___alignment.1865' c390002.adb:(.text+0x1081): undefined reference to `c390002__vehicle__objectDF.1869' c390002.adb:(.text+0x11a0): undefined reference to `c390002__vehicle__wheels.1883' c390002.adb:(.text+0x1781): undefined reference to `c390002__motivators___alignment.2087' c390002.adb:(.text+0x18a0): undefined reference to `c390002__vehicle__wheels.1883' c390002.adb:(.text+0x1e71): undefined reference to `c390002__motivators___alignment__2.2292' c390002.adb:(.text+0x1f70): undefined reference to `c390002__vehicle__wheels.1883' c390002.adb:(.text+0x2531): undefined reference to `c390002__motivators___alignment__3.2497' c390002.adb:(.text+0x2620): undefined reference to `c390002__vehicle__wheels.1883' collect2: ld returned 1 exit status gnatlink: error when calling /home/guerby/install-trunk/bin/gcc gnatmake: *** link failed. gue...@babe:~/tmp$ gnatmake -f -O0 c390002.adb gcc -c -O0 c390002.adb c390002.adb:101:11: warning: unreachable code gcc -c -O0 report.adb report.adb:312:30: warning: index for "NAM" may assume lower bound of 1 report.adb:312:30: warning: suggested replacement: "NAM'First + 2" report.adb:312:33: warning: index for "NAM" may assume lower bound of 1 report.adb:312:33: warning: suggested replacement: "NAM'First + 6" gnatbind -x c390002.ali gnatlink c390002.ali -O0 gue...@babe:~/tmp$ ./c390002 ,.,.
