Hi
Triggered by a remark from Murray that building the Alpha
world takes so much longer than the x86 one I just tried
if I can build a profiled kernel on the Alpha.
It appears that is not possible:
ds10#cd -
/sys/compile/DS10
ds10#make depend
cc -c -O -pipe -mcpu=ev4 -Wall -Wredundant-decls -Wnested-externs
-Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline
-Wcast-qual -fformat-extensions -ansi -nostdinc -I- -I. -I../..
-I../../../include -I../../contrib/ipfilter -DGPROF -D_KERNEL -include
opt_global.h -elf -malign-functions=4 -mno-fp-regs -Wa,-mev56
../../alpha/alpha/genassym.c
cc1: Invalid option `align-functions=4'
*** Error code 1
Stop in /usr/src/sys/compile/DS10.
It seems to originate from
.if defined(PROF)
CFLAGS+= -malign-functions=4
.if ${PROFLEVEL} >= 2
IDENT+= -DGPROF4 -DGUPROF
PROF+= -mprofiler-epilogue
.endif
.endif
On x86 the -malign-functions is a valid option. On alpha it is not.
As this is my first ever attempt at a profiled kernel please bear
with me ;)
