nvptx: Define valid ASM_OUTPUT_ALIGN.
gcc/
* config/nvptx/nvptx.h (ASM_OUTPUT_ALIGN): Define as a C statment.
gcc/doc/tm.texi:@defmac ASM_OUTPUT_ALIGN (@var{stream}, @var{power})
gcc/doc/tm.texi-A C statement to output to the stdio stream @var{stream} an assembler
gcc/doc/tm.texi-command to advance the location counter to a multiple of 2 to the
gcc/doc/tm.texi-@var{power} bytes. @var{power} will be a C expression of type @code{int}.
gcc/doc/tm.texi-@end defmac
gcc/config/nvptx/nvptx.h:#define ASM_OUTPUT_ALIGN(FILE, POWER)
"Empty" is not a C statement, and so in code such as:
gcc/dwarf2out.c- if (lsda_encoding == DW_EH_PE_aligned)
gcc/dwarf2out.c: ASM_OUTPUT_ALIGN (asm_out_file, floor_log2 (PTR_SIZE));
gcc/dwarf2out.c- dw2_asm_output_data (size_of_encoded_value (lsda_encoding), 0,
gcc/dwarf2out.c- "Language Specific Data Area (none)");
gcc/varasm.c- if (align > BITS_PER_UNIT)
gcc/varasm.c: ASM_OUTPUT_ALIGN (asm_out_file, floor_log2 (align / BITS_PER_UNIT));
gcc/varasm.c- assemble_variable_contents (decl, name, dont_output_data);
gcc/varasm.c- if (align > 0)
gcc/varasm.c: ASM_OUTPUT_ALIGN (asm_out_file, align);
gcc/varasm.c-
gcc/varasm.c- targetm.asm_out.internal_label (asm_out_file, "LTRAMP", 0);
gcc/varasm.c- if (align > BITS_PER_UNIT)
gcc/varasm.c: ASM_OUTPUT_ALIGN (asm_out_file, floor_log2 (align / BITS_PER_UNIT));
gcc/varasm.c- assemble_constant_contents (exp, XSTR (symbol, 0), align);
..., GCC warns:

Also, "use" the values, to get rid of that one:

[...]/source-gcc/gcc/final.c:2450:12: warning: variable 'log_align' set but not used [-Wunused-but-set-variable]
int log_align;
