Hi, This patch still doesn't fix the problem.I got this error : "cc -O2 -pipe -march=pentium-m -mtune=pentium-m -fomit-frame-pointer -Wall -W -Wshadow -I./ -c -o fp_isprime.o fp_isprime.c cc -O2 -pipe -march=pentium-m -mtune=pentium-m -fomit-frame-pointer -Wall -W -Wshadow -I./ -c -o fp_prime_random_ex.o fp_prime_random_ex.c cc -O2 -pipe -march=pentium-m -mtune=pentium-m -fomit-frame-pointer -Wall -W -Wshadow -I./ -c -o fp_mul_comba.o fp_mul_comba.c cc -O2 -pipe -march=pentium-m -mtune=pentium-m -fomit-frame-pointer -Wall -W -Wshadow -I./ -c -o fp_sqr_comba.o fp_sqr_comba.c fp_sqr_comba_generic.c: In function `fp_sqr_comba': fp_sqr_comba_generic.c:69: error: can't find a register in class `GENERAL_REGS' while reloading `asm' make: *** [fp_sqr_comba.o] Error 1 make: *** Waiting for unfinished jobs...." I'm using hardened gcc so I switched to vanilla gcc and it was the same.I sent a mail to Tom St Dennis about the issue.He said x86 lacks registers and REQUIRES -fomit-frame-pointer to build.Using -fomit-frame-pointer with a vanilla compiler solved the problem without the patch. For hardened I don't know of any nice way to solve the problem but filtering pie flag allows the package to compile. What I offer is inheriting flag-o-matic and adding: isflag "-fomit-frame-pointer" || append-flags "-fomit-frame-pointer" gcc-specs-ssp && filter-flags -pie to src_compile(). Thoughts?
