// Portable inline-asm data layout directives.  A few data blocks are emitted
// via inline asm to force exact symbol order and adjacency (relied on by the
// asm core and the save-state code).  ELF and PE/COFF differ in section syntax
// and symbol naming (PE/COFF prefixes an underscore), so abstract it here.
// ASM_GSYM exports _sym and keeps a plain sym alias for intra-block references.
