push-ing pragma exportc generates invalid C identifiers

[turbo]

Description

Compiles fine

type r* = object

proc foo(): r {.exportc: "$1".} =
  echo result

Fails:

type r* = object

{.push exportc: "$1".}
proc foo(): r =
  echo result
{.pop.}

Compilation command:

nim -r c repro.nim

Expected Output

none, successful compilation

Possible Solution

No response

Additional Information

No response

[metagn]

It seems like push exportc leaks into the generic instantiation of $ which is pretty undesirable.

[ringabout]

!nim c

type r* = object
{.push exportc: "$1".}
proc foo(): r =
  echo result
{.pop.}

[ringabout]

Thought my PR caused the regression. It seems to be a pre-existing problem. #b8dc58d88 is the superifical reason, which de facto exposed a problem of templates/generics expansion, which might not handle the push pragmas well.

[ringabout]

!nim c

type r* = object

template std[T](x: T) =
  let ttt {.used.} = x
  result = $ttt

proc bar[T](x: T): string =
  # let today {.used.} = 12
  # block:
  #   let today = 623.5
  #   echo today
  std(x)

{.push exportc: "$1".}
proc foo(): r =
  let s = bar(123)
{.pop.}

echo foo()

Indeed, it's an old issue tracing back to 1.0.10. The push pragmas is leaking into the scope of the generics instantiations. Here is the reduced case

type r* = object


proc bar[T](x: T): string =
  let today {.used.} = 12 # an existing pragma ({.deprecated.} for another example) is needed for whatever the reason might be
  block:
    let today = 623.5
    echo today

{.push exportc: "$1".}
proc foo(): r =
  let s = bar(123)
{.pop.}

echo foo()

[ringabout]

It seems that in the function instantiateBody for generics, it should somehow unload/ignore the current OptionEntry.
