Package: gcc-3.2 Version: 1:3.2.1-0pre3 Severity: normal
xine-lib-1-beta2 fails to compile w/ -march=pentium2 (or greater). it will compile w/ -march=pentiumpro or with any -mcpu setting. it looks like a failure in the FP register allocator or the MD for p2+ class cpus. at least to my untrained eye. =) see below for output w/ different march settings. job coriander:~/xine-lib-1-beta2/src/libfaad# gcc-3.2 -march=pentium2 -DHAVE_CONFIG_ H -I. -I. -I../.. -I../.. -I../../include -I../../include -I../../src -I../../sr c/xine-engine -I../../src/xine-engine -I../../src/xine-utils -Wall -D_REENTRANT -D_FILE_OFFSET_BITS=64 -DXINE_COMPILE -O3 -pipe -fomit-frame-pointer -falign-fun ctions=4 -falign-loops=4 -falign-jumps=4 -mpreferred-stack-boundary=2 -fexpensiv e-optimizations -fschedule-insns2 -fno-strict-aliasing -ffast-math -funroll-loop s -finline-functions -I/usr/include/kde/artsc -c cfft.c -MT cfft.lo -MD -MP -MF .deps/cfft.TPlo -DPIC -o cfft.lo cfft.c: In function `passf2': cfft.c:550: unable to find a register to spill in class `FLOAT_REGS' cfft.c:550: this is the insn: (insn 195 193 200 (set (subreg:SF (reg/v:DI 29 rmm0 [94]) 0) (minus:SF (mem:SF (plus:SI (mult:SI (reg/v:SI 1 edx [70]) (const_int 8 [0x8])) (reg/v/f:SI 4 esi [62])) [0 S4 A32]) (reg:SF 8 st(0) [105]))) 533 {*fop_sf_1_nosse} (insn_list 192 (nil)) (expr_list:REG_DEAD (reg:SF 8 st(0) [105]) (nil))) cfft.c:550: confused by earlier errors, bailing out coriander:~/xine-lib-1-beta2/src/libfaad# gcc-3.2 -march=pentiumpro -DHAVE_CONFI G_H -I. -I. -I../.. -I../.. -I../../include -I../../include -I../../src -I../../ src/xine-engine -I../../src/xine-engine -I../../src/xine-utils -Wall -D_REENTRAN T -D_FILE_OFFSET_BITS=64 -DXINE_COMPILE -O3 -pipe -fomit-frame-pointer -falign-f unctions=4 -falign-loops=4 -falign-jumps=4 -mpreferred-stack-boundary=2 -fexpens ive-optimizations -fschedule-insns2 -fno-strict-aliasing -ffast-math -funroll-lo ops -finline-functions -I/usr/include/kde/artsc -c cfft.c -MT cfft.lo -MD -MP -M F .deps/cfft.TPlo -DPIC -o cfft.lo cfft.c: In function `cffti1': cfft.c:428: warning: `ntry' might be used uninitialized in this function coriander:~/xine-lib-1-beta2/src/libfaad# gcc-3.2 -mcpu=pentium2 -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../../include -I../../include -I../../src -I../../src /xine-engine -I../../src/xine-engine -I../../src/xine-utils -Wall -D_REENTRANT - D_FILE_OFFSET_BITS=64 -DXINE_COMPILE -O3 -pipe -fomit-frame-pointer -falign-func tions=4 -falign-loops=4 -falign-jumps=4 -mpreferred-stack-boundary=2 -fexpensive -optimizations -fschedule-insns2 -fno-strict-aliasing -ffast-math -funroll-loops -finline-functions -I/usr/include/kde/artsc -c cfft.c -MT cfft.lo -MD -MP -MF . deps/cfft.TPlo -DPIC -o cfft.lo cfft.c: In function `cffti1': cfft.c:428: warning: `ntry' might be used uninitialized in this function coriander:~/xine-lib-1-beta2/src/libfaad# -- System Information Debian Release: testing/unstable Architecture: i386 Kernel: Linux coriander 2.4.18-686-smp #1 SMP Sun Apr 14 12:07:19 EST 2002 i686 Locale: LANG=C, LC_CTYPE=C Versions of packages gcc-3.2 depends on: ii binutils 2.13.90.0.10-1 The GNU assembler, linker and bina ii cpp-3.2 1:3.2.1-0pre3 The GNU C preprocessor. ii gcc-3.2-base 1:3.2.1-0pre3 The GNU Compiler Collection (base ii libc6 2.2.5-14.3 GNU C Library: Shared libraries an ii libgcc1 1:3.2.1-0pre3 GCC support library.
