Fomit frame pointer gentoo
-fomit-frame-pointer allows one extra register to be available for general-purpose use. I would assume this is really only a big deal on bit x86, which is a bit starved for registers.* One would expect to see EBP no longer saved and adjusted on every function call, and probably some additional use of EBP in normal code, and fewer stack operations on occasions where EBP gets used as a. -fomit-frame-pointer in CFLAGS/CXXFLAGS. you’ll get into troubles! And this is not specific to Gentoo and probably not to specific kernel version, because there are reports from and before ! So if you have the following error. Mar 09, · This has to do with x Without -fomit-frame-pointer parameters and local variables are accessed via the frame pointer %ebp. With frame-pointer-ommision %ebp is used for whatever suits and parameters/local vars are accessed via the stack pointer %esp. Now, for some oddity I'll leave out, memory accesses via %esp are one byte longer than via %ebp.
