+/* PR 25662: objcopy sets invalid sh_offset for the first section in a
+ no_contents segment containing program headers.
+
+ Several conditions are required for the bug to manifest:
+ - The first loadable segment (which contains the program headers) must only
+ contain SHT_NOBITS sections. .bss is the SHT_NOBITS section in this test.
+ - The next loadable segment must have a !SHT_NOBITS loadable section. .data
+ is the !SHT_NOBITS section in this test.
+ - .bss must be positioned after .data in the executable file itself.
+ - The size of .data must be such that the calculated VMA of the .bss
+ section that follows it is not congruent with the file offset of .bss,
+ modulo the p_align of its segment, i.e.:
+ (VMA(.data) + sizeof(.data)) % (.bss_segment.p_align) != 0
+ This will force the sh_offset of .bss to be aligned so it appears within
+ .data.
+ - The size of .data must be larger than the program headers in the first
+ loadable segment, so that the file offset of .bss is immediately
+ after .data, and not padded to a valid alignment by the program headers.
+
+ The bug originally only manifested for ELF targets, but there's no reason not
+ to run this testcase for other file formats. This variant source for pdp11
+ uses .text rather than .section text, etc., because the latter are not
+ supported, */
