This adds the section to HANDLE_ALIGN args, so that the frag created by the ppc backend can be properly allocated on the frag obstack. I've added an extra param to frag_alloc too, for cases where we know the frag requires at least some bytes in fr_literal. This simplifies some existing code, for example in compress_debug and relax_segment. In the case of the relax_segment code, I think we may have had a bug there in using obstack_blank_fast, which doesn't check that the frag has room. * config/tc-ppc.c (ppc_handle_align): Add section param, use frag obstack to allocate frag. * config/tc-ppc.h (HANDLE_ALIGN, ppc_handle_align): Add extra param. * config/tc-aarch64.h (HANDLE_ALIGN): Add extra param. * config/tc-alpha.h: Likewise. * config/tc-arc.h: Likewise. * config/tc-arm.h: Likewise. * config/tc-avr.h: Likewise. * config/tc-epiphany.h: Likewise. * config/tc-frv.h: Likewise. * config/tc-i386.h: Likewise. * config/tc-ia64.h: Likewise. * config/tc-kvx.h: Likewise. * config/tc-loongarch.h: Likewise. * config/tc-m32c.h: Likewise. * config/tc-m32r.h: Likewise. * config/tc-metag.h: Likewise. * config/tc-mips.h: Likewise. * config/tc-mn10300.h: Likewise. * config/tc-nds32.h: Likewise. * config/tc-riscv.h: Likewise. * config/tc-rl78.h: Likewise. * config/tc-rx.h: Likewise. * config/tc-sh.h: Likewise. * config/tc-sparc.h: Likewise. * config/tc-spu.h: Likewise. * config/tc-tilegx.h: Likewise. * config/tc-tilepro.h: Likewise. * config/tc-v850.h: Likewise. * config/tc-visium.h: Likewise. * config/tc-wasm32.h: Likewise. * config/tc-xtensa.h: Likewise. * frags.h (frag_alloc): Update prototype. * frags.c (frag_alloc): Add extra size param, allocate extra. (frag_new): Update. * subsegs.c (subseg_set_rest): Update frag_alloc call. * write.c: Formatting. (cvt_frag_to_fill): Pass sec to HANDLE_ALIGN. (compress_frag): Update frag_alloc call. (compress_debug): Use new frag_alloc to simplify frag sizing. (relax_segment): Likewise.
