[U-Boot] Relocation size penalty calculation

[Graeme Russ]

Out of curiosity, I wanted to see just how much of a size penalty I am
incurring by using gcc -fpic / ld -pic on my x86 u-boot build. Here are
the results (fixed width font will help - its space, not tab, formatted):

Section             non-reloc     reloc
---------------------------------------
.text                000118c4  000137fc <- 0x1f38 bytes (~8kB) bigger
.rodata              00005bad  000059d0
.interp              n/a       00000013
.dynstr              n/a       00000648
.hash                n/a       00000428
.eh_frame            00003268  000034fc
.data                00000a6c  000001dc
.data.rel            n/a       00000098
.data.rel.ro.local   n/a       00000178
.data.rel.local      n/a       000007e4
.got                 00000000  000001f0
.got.plt             n/a       0000000c
.rel.got             n/a       000003e0
.rel.dyn             n/a       00001228
.dynsym              n/a       00000850
.dynamic             n/a       00000080
.u_boot_cmd          000003c0  000003c0
.bss                 00001a34  00001a34
.realmode            00000166  00000166
.bios                0000053e  0000053e
=======================================
Total                0001d5dd  00022287 <- 0x4caa bytes (~19kB) bigger

Its more than a 16% increase in size!!!

.text accounts for a little under half of the total bloat, and of that,
the crude dynamic loader accounts for only 341 bytes

Have any metrics been done for PPC?
